File size problems

Post by Gilbert »

I am saving very large waveform capture files using a 6000 series PicoScope with the .mat (MATLAB) extension. Somewhere at ~350 MB and above the saved files will not load into MATLAB and produces an error stating the files may be corrupt. I'm using as high as possible sampling rates to retain waveform envelope resolution and the 13 MHz sine wave when zoomed in. Lower sample rates introduces aliasing artifacts, loss of envelope resolution and interpolation of the sine wave when zoomed in. I'm using software version 6.14.23.5207 and have 32 GB of RAM. The software seems to be doing something to the files at around 350 MB and above. Any help would be appreciated.

I did find another post here...

...where the user Labrat had the same error that I am getting and Hitesh indicated that they are aware of an issue relating to the export of data to .mat format. It doesn't look like a solution has been determined yet?
