Extracting the intensity contribution from a certain phase for a batch of dataset
Intensity contribution from individual phase can be saved out from GUI interface “right-click → save if displayed…”.
However, there were multiple questions asked in the forum concerning how to extract phase contribution through Launch Mode .inp file setup, and even do this for in-situ data set.
The solution below has been enlightened by the Alan Coelho's 2-step refinement & Matthew Rowles's Sequential Refinement method.
TOPAS V6 allows a keyword num_runs which instructs the programme to run an .inp file multiple times, which means above 2-step solution can be devised in one .inp file with “num_runs 2” and several #if switches:
1. Extracting phase contribution from a single data
num_runs 2
#if (Run_Number == 1)
iters 0
#endif
#if Run_Number == 0;
system_before_save_OUT { copy INP_File##.inp INP_File##.backup } /* Backup this .inp file in the first run. */
#endif
out_file = Concat(String(INP_File), ".INP"); /* This allow the refinement result to be accepted. */
#if Run_Number == 1;
system_after_save_OUT { copy INP_File##.backup INP_File##.inp } /* Restore this .inp file to its initial status from the backup in the final run */
#endif

It can be seen that, in the first run (Run_Number = 0), the #if switches allows a normal Pawley refinement which refines the sample displacement according to an internal standard (hkl_Al in this case).
In the second run (Run_Number = 1), the #if switches only turned on the phase of interest with “iters 0” and get the intensity saved out.
2. Extracting phase contribution from a batch dataset
To apply this method for a batch of data set (e.g. in-situ data set), which contains, say 100 patterns, an .inp file with “num_run = 2 * 100;” can be set as below:
(The restriction of this setup is, the file names of the dataset must contain an increasing run number: e.g. *_1.raw, *_2.raw, ***_3.raw, ….. A simple windows/DOS batch rename can achieve this. )
num_runs =2*100; /* This set the Reserved Keywords "Run_Number" goes from 0 to 199 */
#if (Mod(Run_Number,2) == 1) /* Normal Pawley refinement when Run_Number is an even number; Save the phase intensity when Run_Number is an odd number */
iters 0
#endif
#if Run_Number == 0;
system_before_save_OUT { copy INP_File##.inp INP_File##.backup }
#endif
out_file = Concat(String(INP_File), ".INP"); /* This accepts the refinement result, especially the sample displacement */
#if Run_Number == 2*100-1;
system_after_save_OUT { copy INP_File##.backup INP_File##.inp }
#endif
#prm filenum = Round((Run_Number+1)/2); /* This calculates the run number of the file, NOTE Round(0.5) evaluates to 0 in TOPAS V5, but evaluates to 1 in TOPAS V6! */
