Hello, Sorry if this has been discussed already! I am a new user of TOPAS academic v7. I am trying to do a quantative rietveld refinement for my sample, where I have added 20 wt% corundum standard. I am trying to figure out how to input this weight fraction. I searched the forum and found this: https://topas.awh.durham.ac.uk/doku.php?id=weight_percentage_in_original, where it is directed how to add weight fraction. I followed this but I am getting an error: *** Error loading sstring_in at
{ Spike_amount_in_specimen }
unknown or misplaced keyword.
at LINE 46
See log file C:\Topas\topas.log
A snippet of where I added the weight fraction part:
str
Spike_amount_in_specimen(20, 0)
space_group "P1"
a @ 5.201015`
b @ 5.181923`
c @ 5.196038`

be @ 55.58703`
