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.

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.

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/06_A10_L_y' }

{'Untitled/07_A10_L_z' }

{'Untitled/08_A04_L_z' }

{'Untitled/09_A04_L_y' }

{'Untitled/10_A05_R_z' }

{'Untitled/11_A05_R_y' }

{'Untitled/12_A01_R_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);
