* 'master' of github.com:jefferis/DrosophilidDBM:
  fix: only takes files into account that END in .nrrd. this is to exclude the ones which have stitched names that contain nerd.
  RegionPerm does now what it is supposed to do: it calculates fractional volumes for each np_region for each species. it further calculates whether these fractional volumes differ (nb: could be both rel greater or smaller) from those in Dmel. and it calculates their absolute volumes (i.e. rel*8).
  fix: neuropilmask has to be defined BEFORE it is used by sapply and not AFTER. and commented out the calculation of absolute volumes for the moment
  this is a fix of the default image output (square) so brains images are now generated with proper side ratio
  use try(source()) so R doesn't stop when it fails with Dyakuba but keeps running
  Remove backup ImageProcessingFunctions
  comment out irrelevant code, clean up vstats
  included: cache results of the comparisons
  comment out irrelevant code
  I think a mistake happened here (Dsim) in specifying the tvals that should be used to calculate the isosurfaces for Amira. I corrected that.
