Trouble in reading .tdms file

https://drive.google.com/drive/folders/1SLYPYeZqFFTJnZIeY_VhvrNOBYI1Kv9a?usp=sharing

I tried reading this tdms file, however it shows entries upto 1500 sample size only for a particular channel. I would like to have a table of all channels with their row wise values so that I can access any channel. Additionally, the same tdms file I tried in python entries shows upto 80k rows for a single channel. Is the file size too much to handle in MATLAB, why it is not showing all data and plotting the same for a single channel. Further, can I import this for signal processing toolbox in MATLAB.

Hello @Susmita,

The file "Data1.tdms" is not accessible. Can you please share the downloaded "Data1.tdms" file?

[Susmita]

The file exceeds 5 MB and hence unable to upload and hence by clicking one can download the file as I have provide access to everyone.

hello @Susmita,

I am getting this window when I clicked "data1.tdms"

[Susmita]

Sorry for the trouble. I have uploaded data and code in google drive. Please have a look over it.

The tdmsread function requires the Data Acquisition Toolbos or the Communications Toolbox. It should be available here, except that the files are too large (‘Data1.tdms’ is 135.3 MB and ‘Data1.zip’ is 48.4 MB) to upload to MATLAB Answers, so this has to wait for someone with one of those Toolboxes to see this and read the files offline.

[Susmita]

Thank you @Star Strider. I installed these toolboxes, still I am unable to see entire dataset, only 1500 sample size is what I can see in MATLAB.

[Star Strider]

My pleasure!

My point is that only someone with one of those Toolboxes installed will be able to help you with this.

hello

No toolbox required here - I simply used this Fex submission (files are attached if you prefer the fast way)

ConvertTDMS (v10) - File Exchange - MATLAB Central (mathworks.com)

No problem so far , I could plot the microphone channel to double check

Name Size Bytes Class Attributes

ChanNames 1x1 3092 cell

ConvertVer 1x4 8 char

ConvertedData 1x1 141961792 struct

ChanNames :

{'Untitled/00_A08_L_z' }

{'Untitled/01_A08_L_y' }

{'Untitled/02_A03_L_z' }

{'Untitled/03_A03_L_y' }

{'Untitled/04_A09_L_y' }

{'Untitled/05_A09_L_z' }

{'Untitled/17_A07_R_z' }

{'Untitled/18_A02_R_y' }

{'Untitled/19_A02_R_z' }

{'Untitled/20_Microphone'}

[ConvertedData,ConvertVer,ChanNames]=convertTDMS(true,'Data1.tdms');

% plot last channel (microphone)
plot(ConvertedData.Data.MeasuredData(23).Data);

Thank you @Mathieu NOE that really worked for me.

as always, my pleasure !
