Hi Christoph,

The error lies in the regular expression: replace the "*.his" with ".*.his" and it should work.

By the way: does anyone know have a tutorial on regular expressions for beginners to recommend ?

Dear all,

I want to use rtksubselect to create single geometryfiles for every projection for parallelization purposes. When using the following command:

rtksubselect -g geometryfilename.xml --out_proj subsettest.mha --out_geometry subsettestgeom.xml -f 1 -l 2 -p projectionfolder -r *.his

I get this error:

ExceptionObject caught with paste->Update() in file /scratch-local/rauscher/rtk/RTK/applications/rtksubselect/rtksubselect.cxx line 113

itk::InvalidRequestedRegionError (0x1818600)

Invalid requested region error triggered by ProjectionsReader
img->GetRequestedRegion() = [ ImageRegion (0x180ea40)
  Dimension: 3
  Index: [4, 4, 1]
  Size: [504, 504, 1]
 ]
img->GetLargestPossibleRegion() = [ ImageRegion (0x180ea08)
  Dimension: 3
  Index: [4, 4, 0]
  Size: [504, 504, 1]
 ]
it works for the first file though when using -f 0 -l 1

regards,
Christoph
