• ASCII data logging / or something readable!

  Hi, I was using the attached code to exploit/collect data from a system of GC and it used to be saved as a file in a text which I opened and transfer the data to Excel or laboratory of origin. For some reason, the format that it is written in the file has changed, and if I try to import directly to origin or something like ascii, it now says that the ascii data is not readable by columns. If I try to open in something like a block of text, it just displays as lines of symbols, perhaps ansii?

  I have absolutely no idea of what maybe I changed to do this and how to return to a "readable" format, any help would be greatly appreciated!

  Thanks, Kelly

  OK, convert your DBL timestamp and use the following format (be sure to set the schema format display of \-codes first constant!):

  %.5e\t%.5e\n

• Data analysis for peak max after sampling offsets

  In the attached VI, each channel is to measure a point of acceleration, which appears as a global maximum on the chart. Ideally, what I want to happen is for both tables to search for their highlight (global max) and the difference in time between these two peaks are shown on the screen after that program ended. However, what I have right now is a sort of measure in real time. Any suggestions on going about doing this?

  Thank you

  Hey Johnny,

  Every time that you run in the loop, you recalculate the value of the difference.  When the loop is running again, it clears the value you had before.  There are tons of ways that solve you the problem.  A lot of it depends on if you need data analysis while you're in the loop.  If you want to check it after it's done running, you can connect just the difference on the edge of the while loop and turn on indexing by right-clicking on the tunnel.  This will save the value of the difference of each iteration of the while loop.  You can also save under condition maybe (maybe you only care about the difference if there is between certain values) in writing to a text file by using the writing of text file or by building an array in a structure of housing.  These are just some thoughts.

• Import ASCII dates with different format

  Hello

  I need to import data from a CSV of ASCII.

  The problem is the date format in this particular data file (.csv)

  The date format for day< 10="" and="" month="" from="" jan="" to="" sep="">

  AAAA/_M/_Dthe character '_' is a simple space, not an underscore literally

  The format of the date days > = 10 and Jan to Sep month is:

  _M/JJ/AAAA

  The format of the date days > = 10 and months of Oct to dec is:

  YYYY/MM/DD

  The date format for day< 10="" and="" months="" from="" oct="" to="" dec="">

  YYYY/MM/_D

  Possible solution:

  I already create a routine that recognizes the date in the title and one of the 4 (.stp) filter uses for data processing. These are the works.

  Next problem:

  The days are separated into 2 files, a file from 09:00 to 21:00 one day and the other from 21:00 to 09:00 on the following day. It's the way I've lost data when the day changes from 9th to the 10th of each month and the month change of Sept Oct and Dec to Jan.

  I just need to delete the blankspace unconfortable before the changes of dates 2-digit, but I do not know how to deal with the before CSV imported to tiara (10.2).

  My other idea is to recognize this file and any double (once with each please) but I need to exactly position the import is not the problem with the data of novalue. (Until know I got complicated for a simple mistake of blankspace).

  I hope that you have ideas...

  Thanks in advance...

  I don't know if I understand that measures are not clear. Here's what I think you want to do:

  (1) load data from different files in DIAdem

  To do this, you must use "DataFileLoad("E:\Customer_Requests\caracasnet\log(111231).csv","caracasnet_log","Load") call.

  You call DataFileLoad for each of the files.

  (2) you want to concatenate the groups.
  This should be no different than what you've done up to now

  (3) you want to store the data in a file (TDM).
  To do this, you must call DataFileSave (...)

  Let me know if you have any other questions...

• How to use Labview to send commands to Excel on data analysis

  Hello, here's my situation:

  I have a Labview VI that reads data from various sensors and uses the report generation tool to send all the data values to Excel. Because each race is ~ 8-10 hours long and there is tons of data, I'm not worth it to store them in a table in my VI.

  However, in my Excel report I would like to include some statistics, like the initial report, max and min values of all the data from these points. Should what kind of command I send my VI to get Excel to do this? Or would it be easier to do within Labview instead?

  Thanks to anyone who can give some advice!

  Hello, Kalyie!

  Puneet.Kapoor is indeed correct, you can create an Excel macro and call from LabVIEW. An example of this in LabVIEW under help > find examples. When searching for "Excel", you will find 'Excel Macro example.' It would be more useful for the automation of your functions, or if you try to do more complex operations on your data in Excel (min and max are simple relativelty, however).

  As we have also seen, it may be easier to work with the data once it is in excel, using the '(Max) =' and the functions '= Min ()' - the choice is yours!

• Functions in pipeline for the csv data analysis?

  Hi all

  I currently have a pl/sql procedure that is used to load and parse a CSV file in a table of database within the Apex.

  Downloading csv files are quite large (nearly 1 million rows or more) and there is a time of significant waiting for the course ends. I tried both Wizard 4.2 data that was very slow loading and the apex plugin excel2collection who timed out/never finished.

  I heard functions in pipeline and how they can offer great time savings for insert instructions where the database lines have no interconnect/dependencies to each other.

  My question is, would the data through pipes to offer me a gain with my time insert statements, and if so someone could help me to implement? The current procedure is listed below, less any code validation etc. for readability. The CSV is first uploaded to a table in a BLOB file before be analyzed by the procedure.

  -- Chunk up the CSV file and split into a line at a time
    rawChunk := dbms_lob.substr(bloContent, numChunkLength, numPosition + numExtra);
    strConversion := strConversion || utl_raw.cast_to_varchar2(rawChunk);
  
    numLineEnd := instr(strConversion,chr(10),1);  --This will return 0 if there is no chr(10) in the String
  
  
    strColumns := replace(substr(strConversion,1,numLineEnd -numTrailChar),CHR(numSpacer),',');
  
    strLine := substr(strConversion,1,numLineEnd);
    strLine := substr(strLine,1,length(strLine) - numTrailChar);
     
    -- Break each line into columns using the delimeter
    arrData := wwv_flow_utilities.string_to_table (strLine, '|');
  
      FOR i in 1..arrData.count
      LOOP
    
       --Now we concatenate the Column Values with a Comma
        strValues := strValues || arrData(i) || ','; 
  
      END LOOP;
  
       --Remove the trailing comma
        strValues := rtrim(strValues,',');
  
       -- Insert the values into target table, one row at a time
      BEGIN
        EXECUTE IMMEDIATE 'INSERT INTO ' || strTableName || ' (' || strColumns || ')
                           VALUES (' || strValues ||  ')';
      END;
    
      numRow := numRow + 1; --Keeps track of what row is being converted
  
      
     -- We set/reset the values for the next LOOP cycle
      strLine := NULL;
      strConversion := null;

• How to set up a chart and store data points in a table to allow me to do the analysis with him

  Hello

  I am relatively inexperienced, with the help of labview and I try to do the following with the help of an oscilloscope Tektronix TDS 2001 C but have no idea how start.

  (1) load a previously saved regarding the volts/div and setting s/div on oscilloscope

  (2) pass everything that appears on the o-scope on my computer screen

  (3) save the data table so that I can do a scan with it

  I watched some of the diagrams of block of example provided with the driver I downloaded for this particular unit but am still very confused.  Any help would be greatly appreciated

  Hello Chron0,

  I know I guess a little here, but have you downloaded a specific device of ni.com/idnet driver?  This is a good place to find the built-in drivers for third-party devices, and there is one for this particular model.  That being said, when I looked at the examples in the downloaded zip file, I saw a couple of predefined options that look like they should satisfy question #2 of your project based on the method to use to acquire a waveform (permanently, several waveforms, etc.).  Similarly, in the Public folder is a configuration of channel VI which I think should satisfy what you are wanting to do to the #1 question.

  Depending on what you are willing to do data analysis, with regard to the software used, functions, etc., there are several reporting tools in LabVIEW which will allow you to save the table and manipulate later. A good place to begin with, it will be to search for "File i/o" in the search bar helps LabVIEW and select the option under the heading "Palette."  There are several options here that I think might be useful, including writing in the file.vi worksheet.

  It will be also good to be familiar with the Finder example OR in LabVIEW.  There are examples of spreadsheets / saving data, as well as VISA, which you can do some reading on, because the interface VISA, it's how you communicate with this device (Fortunately, the driver already download it!)

  Good luck to go ahead and keep us informed here on your project!

  Why I get the error "Could not complete your request because of a problem with JPEG data analysis" when I try to open the photo files in the elements (7,0) editor? I was able to open these files in Photoshop, a few weeks ago and now I get an error. This happens to a lot of my files. How can I fix it? Please help me!

  I found a solution, however, only for MAC users:

  Step 1: Download the image to your "downloads" folder

  Step 2: Open your "Photos" on your Mac program.  (I currently run OS El Capitan)

  Step 3: Go to your 'File' menu and scroll down to "import".

  Step 4: When the window opens, go to your folder that you have saved your photo in "downloads".  Click on the name of your photo.

  Step 5: After the opening of your photo, return to the 'File' menu, but this time click 'Export '.  It will have an arrow that goes to the right and click on "export 1 Photo... »

  Step 6: When the window opens, click on the "file type" JPEG to TIFF.

  Step 7: After you change the type of file, go down to the right of the window and click "export."

  Step 8: Click on the location you want to save the file, and then click New at the bottom right on "export".

  The file appears in the folder you selected.  I opened the files with success in different versions of Photoshop (2014 and later versions).

• data storage

  Hello

  I have a few questions about how to manage and store data.

  I am witing a calibration software where I need to display the chart with the probes.

  then table of current vs probe 10 times Ref then calculations such as average, sigma, then conversion and data storage.

  Using data from the previous program files, I have identified a type of format.

  I reproduced it as a cluster with cluster as table follows this im using as a temporary variable when acquiring and pending approval of the user.

  After that I'll have to move from cluster to a vi convert txt to be operated by another application.

  My question is:

  is it a good way cluster using rather vs. string table

  one is typed so much more easy don't make mistake affecting each measure and the data calculated in the right place

  but less if the cluster size has to change

  with an array of strings, change can be easier but it is easy to make the mistake of index and by placing it in the wrong cell

  What would you use?

  Best regards

  Attached cluster VI

  While I agree with Mark that by using the software OpenG is write a much easier configuration file (in fact you can use the variant to the ini cluster just write the table once), it seems you are actually asking how to store data, no?  In this case, the format of configuration file would seem inappropriate if you plot the data that you need another script to extract data from this format.  If you try to write data that the customer can extract, then the way you suggest (without having seen) is not unreasonable.  Have that said, you considered PDM.  There are plugins for playback of this format for several packages of data analysis (Igor, Matlab, Excel, etc.) and writing to the file in this format is child's play.  There were converters even in ascii as others have developed on this site (I have not really tested it).  Anyway, just a thought.

  Cheers, Matt

• Digital acquisition of data streams

  Hello

  I tried (unsuccessfully) to acquire digital data of a sensor laboratory.  The Guide from the manufacturer:

  "When the excitement of voltage, DTC Decagon sensor makes a measurement.  Three measurement values are passed for about 140 ms of excitement to the data logger as a character of flow series of ASCII.  The series is 1200 asynchronous baud with 8 data bits, no parity and one stop bit.  The voltage levels are 0-3, 6V and logical levels are (low active) TTL.  The power must be removed and repeated his request for a new set of values to pass.  The ASCII data stream contains three numbers separated by spaces.  The first number is the depth of the water in mm, the second number is the temperature in degrees Celsius, with a resolution of 0.1 degree C, and the third number is the electrical conductivity in dS/m, with a resolution of 1 dS/m.  A carriage return follows the three digits, then the character ' t "", which indicates that it is a sensor DTC, and then a control character, and finally a carriage return and supply line. ' "

  My attached VI is a little dubious-it probably looks like something that someone used for analog signals may create.  However, I was hoping it would be enough of a starting point for a more wise to work with LabVIEWer.

  Thank you very much

  Lacksagoo

  The guide said in reality as a data acquisition card OR is the same as a data logger. I've never associated the two as being the same. What I think about a data logger is an autonomous instrument.

  Looking for a more details in your original post, the voltage levels are not standard. You may need a shifter level or need to find a USB-RS232 adapter for TTL levels.
