Dear all, We are working on structure refinement using the Time-of Flight data collected in the ISIS Polaris, in UK. We are using the GSAS software. Could anyone tell us what is the correct format for the TOF data input file for the GSAS refinement? And how to make it if it is different from the data format we have which is: Bin no. x y e 1 200.6388 3.964094 0.1950043E-01 2 201.8044 3.906375 0.1908529E-01 3 203.0007 3.911664 0.1934239E-01 ... Thanks a lot! Renyang
