Thanks Jakub. I used your function to read AFM data from Asylum Research AFM. This saves me so much time analyzing drift data.

I used to use this function and it worked exceptionally. I am now using a different acquisition software, which still create IBW files on Igor Pro, but I'm unable to load them on MatLab. When I try, i get this error: Error using readIBWbinheader (line 31)
Cannot read version 1280 IBW files - only versions 2,5 are okay.

Is there a way to fix it? Should I modify the Igor Pro script or is there something I can do directly on MatLab? Any suggestion on how to cnvert those files?
Thank you very much!

Hi Sandy, open your pxt file with Igor and save it as .pxu (unpacked) format. As soon as you do this, Igor will create a folder in the file's directory with .ibw files in it.
