Can you post the text of your launcher script?  Only one task is run at a time inside the pipeline, so the issue will be there.

Peace,

Matt.

Subject: [HCP-Users] error when processing more than 2 tasks with GenericfMRIVolume script

We’ve run into a weird problem when using the GenericfMRIVolume batch script to process more than 2 tasks at a time. When we setup any more than 2 tasks (we’ve tried 3 and 4 tasks), the first 2 run correctly and without error, but any after that crash in the TopUp section with the following error (the failed tasks all get to the same point):

 

# RUN TOPUP

# Needs FSL (version 5.0.6)

${FSLDIR}/bin/topup --imain=${WD}/BothPhases --datain=$txtfname --config=${TopupConfig} --out=${WD}/Coefficents --iout=${WD}/Magnitudes --fout=${WD}/TopupField --dfout=${WD}/WarpField --rbmout=${WD}/MotionMatrix --jacout=${WD}/Jacobian -v

Part of FSL (build 506)

topup

 

Usage:

topup --imain= --datain= --config= --coutname=my_field

 

 

Compulsory arguments (You MUST set one or more of):

                --imain                  name of 4D file with images

                --datain                name of text file with PE directions/times

 

Optional arguments (You may optionally specify one or more of):

                --out                      base-name of output files (spline coefficients (Hz) and movement parameters)

                --fout                    name of image file with field (Hz)

                --iout                     name of 4D image file with unwarped images

                --logout                Name of log-file

                --warpres            (approximate) resolution (in mm) of warp basis for the different sub-sampling levels, default 10

                --subsamp          sub-sampling scheme, default 1

                --fwhm                 FWHM (in mm) of gaussian smoothing kernel, default 8

                --config                Name of config file specifying command line arguments

                --miter                  Max # of non-linear iterations, default 5

                --lambda              Weight of regularisation, default depending on --ssqlambda and --regmod switches. See user documetation.

                --ssqlambda       If set (=1), lambda is weighted by current ssq, default 1

                --regmod             Model for regularisation of warp-field [membrane_energy bending_energy], default bending_energy

                --estmov             Estimate movements if set, default 1 (true)

                --minmet             Minimisation method 0=Levenberg-Marquardt, 1=Scaled Conjugate Gradient, default 0 (LM)

                --splineorder     Order of spline, 2->Qadratic spline, 3->Cubic spline. Default=3

                --numprec          Precision for representing Hessian, double or float. Default double

                --interp                Image interpolation model, linear or spline. Default spline

                --scale                   If set (=1), the images are individually scaled to a common mean, default 0 (false)

                --regrid                 If set (=1), the calculations are done in a different grid, default 1 (true)

                -h,--help              display help info

                -v,--verbose       Print diagonostic information while running

                -h,--help              display help info
