I'm working with same data measured using the DECTRIS PILATUS3 X 2M CdTe.
When only integrating a select azimuthal range, the data therefore has some gaps in 2θ.
In Topas v6 it was possible to have NaN as the observed intensities in .xy files and TOPAS seemed to parse the file just fine, but treated them as 0's.
In Topas v7 this does not seem to be the case any longer.
I haven't been able to find any documentation in the technical reference (Table 17-4 and 17-5 in section 17.25) or on the forums that says this was actually "allowed" previously, so maybe I was just lucky that it worked.
Is it possible to re-enable it? Or is it allowed in another file format?
Or even better, does any of the other accepted file formats automatically exclude/ignore NaN intensities?
For plotting reasons I would prefer to keep equidistant 2θ steps rather than simply removing the entries.
My alternative is currently to set the intensities to -2, but the still necessitates that I manually write the excluded regions.
A second thing I was wondering, was if it was possible to write NaN to Yobs/Ycalc/Ydiff when using a macro such as Out_Yobs_Ycalc_and_Difference(file)?
Any help would be much appreciated!

Hi
The program does not recognize NaN. If the data file has such text then remove the text using a good editor or write a small program to do so.

I don't think this is possible.
cheers
