[Castor-users] Normalization

[FILIPOVIC PIERUCCI Marina]

Hi,

For reconstructing list-mode data, you need to provide additional information for sensitivity computation, so either a sensitivity image or a CASToR normalization datafile, this is explained in the documentation in detail. Your reconstruction command needs either -sens or -norm options.

Hi All,

I am trying to reconstruct a dataset with the normalization correction factors included in the listmode data.  I am getting the following error when I submit for reconstruction:

***** The following error message was issued by MPI instance 0
***** oSensitivityGenerator::InitializeNormalizationFiles() -> Normalization correction is included in the data file while it is not in the sensitivity computation !

Here is the reconstruction command:

castor-recon -df   LM_df.Cdh  -opti MLEM -it 2:4 -proj joseph  -dim 256,256,309 -vox 2.73,2.73,1.6  -dout my_images

Please notice that I don’t have a sensitivity image.

Any help would be very appreciated.

Regards,
Sadek
