error in datagrabber

[rickys]

I am trying to run the below datagrabber:

#grab copes, varcopes, and transforms

datasource = pe.Node(interface=nio.DataGrabber(infields=['subject_id'],

                                               outfields=['transforms', 'cope1s', 'cope2s', 'varcope1s', 'varcope2s']),

                     name = 'datasource')

datasource.inputs.base_directory = '/mnt/nfs/proj/delab/Ricky/RoE/workingdir'

datasource.inputs.template = '*'

datasource.inputs.field_template = dict(transforms='registration/_subject_id_%s/%s',                                                   # transforms

                                        cope1s='modelfit/_subject_id_%s/conestimate/mapflow/_conestimate0/cope1.nii.gz',               # cope1s

                                        cope2s='modelfit/_subject_id_%s/conestimate/mapflow/_conestimate0/cope2.nii.gz',               # cope2s

                                        varcope1s='modelfit/_subject_id_%s/conestimate/mapflow/_conestimate0/varcope1.nii.gz',         # varcope1s

                                        varcope2s='modelfit/_subject_id_%s/conestimate/mapflow/_conestimate0/varcope2.nii.gz')         #varcope2s   

datasource.inputs.template_args = dict(transforms=[['subject_id', ['standard_register/transform1Warp.nii.gz', 'standard_register/transform0Affine.mat', 

   'structural_register/transform1Warp.nii.gz', 'structural_register/transform0Affine.mat']]],

                                       copes1=[['subject_id']],

                                       copes2=[['subject_id']],

                                       varcopes1=[['subject_id']],

                                       varcopes2=[['subject_id']])                     

But I am getting the below error:

raise TypeError(e.message + ": Template %s failed to convert with args %s"%(template, str(tuple(argtuple))))

TypeError: not all arguments converted during string formatting: Template /mydir/* failed to convert with args ('1000-D-1',)

Interface DataGrabber failed to run.

I am simply passing in the list of subjects in subject_id. Any ideas what I might be messing up? Similar code I have run perfectly fine with other data sets, and I don't see any differences here...

Thanks,

-Ricky

hi ricky,

this seems strange as there is no template '/mydir/*' that i can see in this datagrabber. are you positive this is the datagrabber that crashes?

cheers,

satra

Hi Satra,

Thanks for the response. This was the datagrabber that crashed, but I fixed it simply by removing the field_template and just using a more general template like this:

datasource.inputs.template = '%s/_subject_id_%s/%s'

and then i used the appropriate template args dict. I am not sure why this error came up, but the field_template worked on all my other pipelines. Strange.

Thanks for the help! -Ricky
