[Castor-users] CasToR Benchmark test

[Fedor Goncharov]

Hello everyone and CasToR team,

I am just a beginner for using CasToR, so I have a simple question
(maybe there is a better mailing list for my question).

I have CasTOR v.2.1, compiled with a Make file under Linux Mint
with an MPI flag. I try to run a benchmark PET-benchmark-histogram v2,
and I get the following error:

==============================================================================================
Reconstruction is going on. Should take from one to several minutes
depending on the hardware.
==============================================================================================
sOutputManager::InitOutputDirectory() -> Output path is
'benchmark_pet_histogram_challenger'
castor-recon() -> Launch reconstruction from CASToR version 2.1.
sScannerManager::BuildScannerObject() -> Start building
sScannerManager::InstantiateScanner() -> Instantiate the scanner geometry
structure
iScannerPET::Instantiate() -> Create scanner structure and read parameters
from configuration file
sScannerManager::GetGeometricInfoFromDataFile() -> Look for acquisition
specific settings into datafile header
sScannerManager::BuildLUT() -> Generate the geometric Look-Up Table
iScannerPET::BuildLUT() -> Build LUT for scanner elements coordinates and
orientations
sScannerManager::Initialize() -> From scanner PET_GE_SIGNA_PET-MR
iScannerPET::Initialize() -> Initialize remaining stuff for scanner to be
ready
***** oImageDimensionsAndQuantification::CheckParameters() -> Should
provide a strictly positive number of threads !
***** The following error message was issued by MPI instance 0
***** castor-recon() -> A problem occurred while checking image dimensions
parameters !
***** Exit function called. Abort with code 1.

==============================================================================================
Check benchmark results (compare reconstructed image with the reference one)
==============================================================================================
***** Input header file 'benchmark_pet_histogram_challenger_it2.hdr' is
missing or corrupted !

Could one help to find the reason for this error and how to fix it?
I am not sure that MPI is really on. is there is a command to check with
witch flags my CasToR
compiled?

Best,
Fedor
