I used XFIT to find peak positions and export them. By this way, the peak positions DO be in an ascending order of 2-theta. In Crysfire, just load command, then the program pops up lines needing sorting. I do not think there is any possibilty for mistakes here. Even I reload the data, the same problem. Does anyone have idea what is wrong? Thanks.
