Input files :

.DAT data files with the following format (ASCII):

line 1 : name of sample (string)
line 2 : note (string)
line 3 : starting angle
line 4 : last angle
line 5 : step
line 6 : time
line 7 : intensity of the 1st point
line 8 : - " - 2nd
. .
last line : - " - last point

.SIM calculated pattern in the same format as above

(the format can be changed in the formatting line, see Configuration file)

.RIE data from the Rietveld program in the format :

line 1 : name of sample (string)
line 2 : note
line 3 : not used
data in columns X Y(exp) Y(calc) Difference

.BAR file containing only peak positions and intensities in the format :

line 1 : name of sample (string)
line 2 : note (string)
line 3 : number of peaks
line 4 : h k l position intensity of peak 1
. . . . . .
line 5 : . . . . . of the last peak

Output files :

.GRF output file in the format suitable for graphical or some spreadsheet programs

columns: angle intensity calculated intensity

.PLT output file for HP 7574A plotter in HP-GL language (taken latest graph from Graphics )

.PRN list of profile parameters of the peaks of the current phase in the current file . The parameters are specified by Listed parameters in Output .

.FIT like .PRN, but with the parameters of fitted function

.PCX graphs in PCX format
