Batch convert .psdata files to .mat files
Batch convert .psdata files to .mat files
I have a bunch of .psdata files, each of them contains several waveforms (taken sequentially)--some of them contains 3, some contains 2 and the other contains 1. Now I want to batch convert the 1st waveform in each .psdata file into .mat file. 1) I tried picoscope /c c:\*.psdata /f mat /q /b. This command converted the last waveform in each .psdata file into .mat file, which was not what I wanted.
2) Then I tried picoscope /c c:\*.psdata /f mat /q /b 1:1. This command converted the last waveform in each .psdata file into .mat file. But the process got stuck at the .psdata files which contains only 1 waveform.
3)Then I tried picoscope /c c:\*.psdata /f mat /q /b all. This command converted all waveform in each .psdata file into .mat files. But the process also got stuck at the .psdata files which contains only 1 waveform.

Re: Batch convert .psdata files to .mat files
Hi liangyin,
It appears that there is a bug in the conversion process so I will report this.
Please note that with the data files with multiple waveforms, the default waveform to convert will be the last one if you use
Instead use
For now, if possible, convert your data files containing a single waveform in a separate directory using the following:
I hope this helps.

picoscope /c "C:\\*.psdata" /f mat Re: Batch convert .psdata files to .mat files
This is great stuff. The answer I was looking for was in the original post.
NB the system call can be made from the Matlab prompt:
system('picoscope /c *.psdata /f mat /q /b all')
Providing your Matlab workspace contains the '*.psdata' files you are trying to convert.
The spectrum analyser options seem unavailable from opening *.psdata into PC Oscilloscope Version: 6.10.11.15
Are more options available in real time than can be used in post processing? Had the spectrum analyser been available for reloaded *.psdata, I may not have needed Matlab at all...
P.S. saturated time traces contain both +'ve and -'ve infinities in the converted *.mat files. These features are what sets PicoTech scopes above the rest.

(one should regard the plural of infinity with the same suspicion as the collective noun for hermits).

Hi JWard,
The same FFT options should be available when collecting data and post-capture.
It is possible to add a Spectrum View once you have captured data in order to view the data in the frequency domain.
There are two ways to do this:
1. From the menu click Views -> Add View -> Spectrum, or
2. Right click in the oscilloscope display and select Add View -> Spectrum
As long as the Viewport is selected, you can then export the data to .mat from PicoScope 6 or you can use the batch conversion process as well naming the Viewport to use.
Hope this helps.
