Click on the 'OK' button will open a dialog box to select the diffractometer
used to record the 'cimen.dat' file: the resolution of the diffractometer has to
be know to create a .PCR input file for FullProf.
'cimen_1.pcr' and 'cimen_2.pcr' files are then generated and can be edited
by clicking on the
'External Applications / Edit .PCR file' menu option.
