thank you for pointing out the problems. I have implemented an empty Reset() function in the PndFtsDataAccessor and modified CMakeLists.txt as follows.
set(DEPENDENCIES Base GeoBase ParBase PndData TrkBase Spectrum)
Sorry that it took me so long to react to your post, I was assuming that I would receive emails from the forum again. I noticed a couple of days ago that this feature seemed to be broken and tried to fix that by resubscribing, but it seems that it did not help.
