Hi Doug, I am running fsfast preprocessing on my data and I am getting an error on one of the runs.
This is the preprocessing code that I run: preproc-sess -s 130321_xu_Object4catmulti_01 -per-run -sliceorder siemens -fsd bold -fwhm 0 -mni305-2mm -surface self lhrh The error seems to happen during the fsl registration on the last run (out of 12 runs): /ncf/vcn/Maryam/mri-space/studies/Obj4catmulti/unpackdata/130321_xu_Object4catmulti_01 flirt.fsl -ref bold/018/tmp.bbregister.1228/fslregister/refvol.fslregister.nii -in bold/018/tmp.bbregister.1228/fslregister/movvol.fslregister.nii -bins 256 -cost corratio -dof 6 -searchrx -90 90 -searchry -90 90 -searchrz -90 90 -verbose 0 -omat bold/018/tmp.bbregister.1228/reg.init.dat.fsl.mat -init bold/018/tmp.bbregister.1228/fslregister/fslmat0.trans.mat -schedule /ncf/apps/freesurfer-5.1.0//bin/flirt.newdefault.20080811.sch terminate called after throwing an instance of 'NEWMAT::SingularException' Abort ERROR: flirt bellow is the register-sess log file. I have only included the section for the registration of the last run. I have looked at the raw data of this run and it does not look different from the other runs (all other runs are successfully registered). I am running freesurfer 5.1. Any idea how I can fix the error?
