AstroImage.write1 function does not work in windows

[michayesh]

Matlab 2023b Windows 10 Enterprise on AP-EO-ERAN-PC Generated a flat image Astroimage and tried to save it as a fits file with write1 function using: kboFlat.write1('kboflat_win.fits'); After about 30 sec this message appeared: Out of memory. This problem exists with other Astroimages.

Tried Matlab fitswrite command for the image data - worked fine - no problem.

Tried the same command on my Ubuntu 22.04 laptop - the function worked fast and perfectly .

theory: maybe related to relPath2absPath - maybe not working well in windows?

Your theory is correct. Just checked tools.os.relPath2absPath function on the win10 pc - gives "out of memory message". It seems that the function calls itself near the end in the case of "no change" - (line 70) and this causes an infinite loop?

Meanwhile use write1 with 'SanifyPath',false,...
