How to filter the traces of tension TDMS after acquisition?

Simple question. We have acquired a lot of electrophysiological data with express signal. We now need to filter data after the acquisition for later analysis. I can import the files TDMS tension of previous experiences, but can't seem to run the filters we used on the side of the acquisition to filter the existing traces. Is there a simple way to do this?

Hello Chinchilla,

I enclose a few screenshots on how to add a step to an analog input filtering. You can select the type of filter and order too.

In this screenshot you can check how to change the configuration of the filter

Finally, you can access the TDMS of LabVIEW file with one of the examples of PDM. Please follow these instructions:

1. open LabVIEW

2 - go to help > find examples to open the Finder 'example '.

3 - Go to Fundamentals > file Input and Output > TDMS > Standard Read and Write and select the VI named TDMS read Events.vi

You will need to know the data present in the file to read correctly. For this, you can use the leading PDM Viewer VI:

http://zone.NI.com/reference/en-XX/help/371361K-01/Glang/tdms_file_viewer/

Or you can use the Toolbox for excel: http://www.ni.com/example/27944/en/ (allows you to transfer the data to Microsoft Excel).

4. After reviewing the data, you will need to apply a filter. You can find the filter functions in the range of Signal Processing.

Please let me know if you have any questions on this subject.

Kind regards

    Thank you

    If the column was purely digital, why cast to CHAR? The OP can do everything suggested Robert Angel. My suggestion was where there was some other non-numeric values in the column that could be the reason why the column is CHAR, then using the SIMILAR filter operand would solve this problem.

    The first part of your suggesting was not necessary if the column is a numeric data type and the second part was just a repetition of what Robert.

  • How to filter the elements of web application with element Boolean field is checked (true) in module_webapps

    Maybe I forget something in the docs of BC but I can't find an answer to my question.

    How can I filter the web app items when a web-app-point-Boolean field (= true) in the backend?

    The web application itself is a list-web-app. What I want to achieve is, that when the web-app-point-field is selected, the web - app element (and its web-app-point-fields) will be displayed on the web page.

    The web page contains code that refers to the web-app-point-fields

    Hope you can help me with this.

    Thank you

    Sincerely, Carla

    Are you referring to the return of the page, using liquid, if the box is checked?

    For the rendered Liquid, you can do this:

    {% If this.} {["My Boolean field'] == '1'-%}

    The Boolean field is checked, show some fields or information are here.

    {%-%}

    The Boolean field is not checked so that you can show what you want here.

    {endif %}

    If you don't want to show anything if it is not checked, then proceed as follows:

    {% If this.} {["My Boolean field'] == '1'-%}

    Go only if it is enabled.

    {endif %}

  • How to filter the file type and size during uploadind files in APEX

    Hello

    I was wondering how I can do to validate the size of a file, before moving in my table? I want to filter the type of file, but for this one, I think I can use regular expressions in a validation process.

    I don't know if there is a way to read the size of the file, even before sending it into the temporary table.

    Thank you

    Bodart

    Hi salma,

    As far as I KNOW, you need to create a validation APEX (PL/SQL Returns Boolean or returns error text), which interrogate the details of the table apex_flow_files file. Here you can get the file type and size etc.

    So just to validate and if the validation fails, then delete the apex_flow_files and riase error message file.

    Kind regards
    Hari

    P.S. Please note that, if there are other validations apex on your page, and if they fail, always apex will load the file in the apex_flow_files table. It is sensible to create a validation (PL/SQL) that will trigger (condition) when online validation errors occurred. Make sure it is the LAST commit on your page in the sequence. And here you can write code to delete the table apex_flow_files.
