Mandatory FreeSurfer installation should be documented and checked for

[hujb48]

HI, It is a great work and when i use mriqc, some errors appears. when I input mriqc test/ test_out/ participant --participant-label 01 some errors appears: traits.trait_errors.TraitError: The 'model' trait of a _SynthStripInputSpec instance must be a pathlike object or string representing an existing file, but a value of '<undefined>' <class 'str'> was specified. and the whole info in cmd is: (mriqc38) hu@hu-LEGION-REN7000K-26IAB:~/PycharmProjects/pythonProject$ mriqc test/ test_out/ participant --participant-label 01 221012-14:06:04,650 cli IMPORTANT:

so what can i do to deal with the problems?

[hujb48]

my dirs' structure is:

-test
 --sub-01
 --sub-02
 --sub-03
  ....

which is suitable for BIDS format.

Could someone address this issue?

i meet the the same problem! Could someone address this issue?

Looks like you need a version of FreeSurfer with the synthstrip models packaged.

_default_model_path = Path(_fs_home) / "models" / "synthstrip.1.pt" if _fs_home else Undefined

I assume FreeSurfer 7.2 or 7.3 would have that?

Hi everyone,

I have the same issue. I followed the "bare metal" installation instructions (here https://mriqc.readthedocs.io/en/latest/install.html) and there is no mention of Freesurfer installation. Is it mandatory for MRIQC ?

@flyfox2022 @hujb48 did you find a solution ?

Thank you very much

@manuegrx The latest versions of MRIQC use SynthStrip, which is a FreeSurfer tool. That should be added to the documentation. This is not configurable, as I understand it.
