I used the GSSpcWrite to create an SPC file by using data read from a TXT file. The SPC file was created successfully and I was capable of reading and plotting it from Matlab. However, I can’t open that file in any other software like Ominc for example. The x axis is not evenly spaced. When I produced a file with an evenly spaced x axis I could open it in Omnic. Any suggestions to make the unevenly spaced x axis SPCs produced by GSSpcWrite open in Ominc (or other spectral software). Regards

You make uneven axis to even axis and save to file.

KSSV thank you for your reply. Is there a certain function to make the x axis even? In my example, I simply replaced the x axis data with randomly generated data that was evenly spaced, but of course I lost my original x axis data. Any suggestions to make my x axis values even? Thank you

You can do it by interpolation. If it is a 1D problem go through interp1. If it is a 2D go through interp2.
