The description of my question was not submit successfully.
There is a .psdata files which was acquired in 2014,now I can't to reacquire waveform again.
The .psdata files consists of 500M samples,I need to analyze waveform datas with Matlab,so I must save the .psdata file as .txt or .csv or .mat.Unfortunately,for 500M samples is too much which exceeds the limit of TXT and Excel,and Matlab also can't open .mat file.
I can Compromise,as the picture shows,the useful waveform data may be from 0s to 260ms,so do you have any ways to save 0s to 260ms waveform data as .txt or .csv or .mat or the other file that Matlab can open?
