I was following along with the instructions on this page: [advancedphotonsource.github.io/GSAS-II-tutorials/FitPeaks/Fit Peaks.htm](https://advancedphotonsource.github.io/GSAS-II-tutorials/FitPeaks/Fit Peaks.htm)
I am able to successfully reproduce the fits using the exercise file data, but when I try to use my own data, the Cell Index/Refine / Index Cell command doesn’t return any results. It does produce indexes for the peaks in Index Peak List, but they don’t match very well.
Any idea what I am doing wrong? I’m not using a .prm file; do I need that?
