In such a case, the user has previously to create a PCR input file for FullProf corresponding to the refinement of the first pattern in the list. During the FullProf cyclic run, the results of the refinement of pattern #n will be used as starting point for refinement of pattern #n+1. Consequently, the changes from one pattern to the following has to be soft and continuous, since all pattern refinements are performed in the same conditions.
The filename of the diffraction patterns is created by a common prefixe part and a second part corresponding to the numbering of data files. In the present example that is dealing with data files called ho_0541.dat, ho_0542.dat ... ho_0550.dat, the prefixe part will be labelled to ho_0 and the first and last number 541 and 550.
Data file format:
The following data files format are strongly recommended: INSTR=5, 6 for neutron diffraction patterns or any format containing the real value of the external variable parameter.
PCR input file for FullProf
Putting the rpa to -2, a file with extension .seq is generated: this file contains a summary of effectively refined parameters together with their symbolic names. This .seq file can be read by WinPLOTR that lets the user select the refined parameters he want to plot versus the extenal parameter (temperature, ...).
The sequential refinement is performed through a command line that is launched from WinPLOTR, invoquing the console version version of FullProf (wfp2k). This version can be explicitaly defined in the winplotr.set setting file, in the [RUN PROGRAMS] part as:
FP_console = fp2k ! FullProf DOS version ! DOS version
If not defined; the "fp2k.exe" program will be used as default version.
