Error on the step of asl_correction, number of TIs unmatch

[XiaoyuXu750]

Hi hcp-asl team,

I met an error on the step of asl_correction when running hcp-asl pipeline on HCPD data. I successfully installed hcp-asl pipeline and set up the environment.

Here is my executive command:

studydir=/ibmgpfs/cuizaixu_lab/xuxiaoyu/HCPD/bidsorig
subid=$1
export StudyFolder="$studydir"
struct=$studydir/${subid}/T1w/T1w_acpc_dc_restore.nii.gz
sbrain=$studydir/${subid}/T1w/T1w_acpc_dc_restore_brain.nii.gz
mbpcasl=$studydir/${subid}/mbPCASLhr/${subid}_V1_MR_mbPCASLhr_PA.nii.gz
fmap_ap=$studydir/${subid}/mbPCASLhr/${subid}_V1_MR_PCASLhr_SpinEchoFieldMap_AP.nii.gz
fmap_pa=$studydir/${subid}/mbPCASLhr/${subid}_V1_MR_PCASLhr_SpinEchoFieldMap_PA.nii.gz
WMPARC=$studydir/${subid}/T1w/wmparc.nii.gz
RIBBON=$studydir/${subid}/T1w/ribbon.nii.gz
cores=4
Atlas=/ibmgpfs/cuizaixu_lab/xuxiaoyu/softwarepackages/hcp-asl/hcpasl/resources/vascular_territories_atlas.nii.gz
Labels=/ibmgpfs/cuizaixu_lab/xuxiaoyu/softwarepackages/hcp-asl/hcpasl/resources/vascular_territories_atlas_labels.txt
outdir=/ibmgpfs/cuizaixu_lab/xuxiaoyu/HCPD/aslresults

echo "running hcpasl for ${subid}"
# hcpasl
hcp_asl --studydir $studydir --subid ${subid} -s $struct --sbrain $sbrain --mbpcasl $mbpcasl --fmap_ap $fmap_ap --fmap_pa $fmap_pa --use_t1 --wmparc $WMPARC --ribbon $RIBBON -c $cores --outdir $outdir -v

And I tested this script on one subject 'HCD0001305'. The error occurred on the step of asl_correction.

fabber.api_cl.FabberClException: FabberException: 1: Invalid value given for option: ti<n>=5 (Number of TIs does not match number of volumes in data)

I checked the files generated by the program interrupt, the volume number of tis.nii.gz is 86, tis_mtcorr.nii.gz is 86, and tis_mtcorr_odd & tis_mtcorr_even both have 43 volumes.
Do you have any suggestion about how to avoid this error?

Thanks a lot!
With regards,
Xiaoyu Xu

Hi Xiaoyu,

Sorry we never replied to this comment, I didn't get a notification. I assume this is no longer a live issue for you?

thanks
