TKD: SHT preparation and indexing errors

[Habakuk224]

I have run into two issues when trying to index TKD pattern:

mp2sht issue

The mp2sht assumes *.h5 file generated for standard EBSD geometry (backscatter) using EMEBSDmaster etc. When trying to parse h5 file for TKD geometry, errors occur due to the different node naming ('TKDmaster'/'EBSDmaster', 'MCfoil'/'MCOpenCL', etc.). I was able to go around this by renaming the respective nodes in h5 file, but then I ran into another issue:

Tilt check issue

There is a sanity check for abs(90°-sTlt+dTlt) < 90° (i.e. the detector can see the sample). However, for TKD sTlt = -20°and dTlt = 10°, resulting in an error "pattern center not on detector".

Could the TKD geometry be somehow taken into the accout? Thanks!

Hi, well, yes, in principle these programs can be adapted to work for TKD as well.  Currently, I do not have the time nor the person power to make those changes, and I don't anticipate this changing any time soon.  But since this whole package is open source, you (or anyone else) are more than welcome to attempt these additions and modifications yourself... If you get it to work correctly we will happily incorporate your changes into the package and make it available to everyone... Regards, Marc.
