[hermann74]

batch name and line

3dTstat -sos -prefix - gmean.errts.unit.1D\' > out.gcor.1D

see in nidm-example :
https://github.com/incf-nidash/nidmresults-examples/blob/dfbcca00d59e58ba1ecee02f9788d89cd9ecb243/afni_default/subject_results/group.DS0011/subj.sub_001/proc.sub_001#L312

Usually -prefix is followed by an output and not character "-" ! Here , an artificial entities with label "-" is created

Describe the expected ground-truth ?

Currently, this command is treated as such:

      {
        "@id": "urn:53a89cdd-70b9-4db2-b069-8c90ee557888",
        "label": "3dTstat",
        "associatedWith": "urn:7c5d805c-8cc9-4593-99f1-fc70e69f54c5",
        "command": "3dTstat -sos -prefix - gmean.errts.unit.1D\\' > out.gcor.1D",
        "parameters": {},
        "used": [
          "urn:e6c16bf5-9ebb-466b-bacc-55dedb5ee0f8"
        ]
      }

      {
        "@id": "urn:e6c16bf5-9ebb-466b-bacc-55dedb5ee0f8",
        "label": "out.gcor.1D",
        "prov:atLocation": "out.gcor.1D",
        "digest": {
          "sha256": "745e3eab454b924aa638496a17e307c12cb1f82d291eda213bd03fb80a3cfbfc"
        }
      }

gmean.errts.unit.1D is considered as the output and there is no input entity.
