MPM example

[tiborauer]

Regarding the examples, the current version contains a template
sub-<participant_label>[_ses-<session_label>][_<indexable_metadata>-<index>][_acq-<label>][_part-<mag/phase>][_ce-<label>][_rec-<label>][_run-<index>]_<suffix>.nii.gz,
so the MPM example should be:

• sub-01_echo-1_acq-MTon_part-mag_MPM.nii.gz
• sub-01_echo-1_acq-MToff_part-mag_MPM.nii.gz
• sub-01_echo-1_acq-T1w_part-mag_MPM.nii.gz
  (i.e. "acq" before "part")

Please see this branch, where I changed file names. Remaining steps:

• Collapse sub-01_acq-MToff_MPM, sub-01_acq-MTon_MPM and sub-01_acq-T1w_MPM json files into one file called sub-01_MPM.json.
• Edit json files with respect to the changes.

[tiborauer]

AFAICS, the images in the MPM folder still follows the previous order:
E.g.:

• sub-01_echo-1_part-mag_acq-MToff_MPM.nii.gz (i.e. "part" before "acq")

@tiborauer thanks for the heads up, you're right. I will correct them as I edit json files.

        sub-<participant_label>[_ses-<session_label>][_<indexable_metadata>-<index>][_acq-<label>][_part-<mag/phase>][_ce-<label>][_rec-<label>][_run-<index>]_<suffix>.nii[.gz]

@agahkarakuzu thank you for nice fixes on the MPM example!

I'll start working on that branch as well to create the 'derivatives' folder - happy to help with the json files as well if useful, or I can give it a quick proof-read afterwards. I had a quick look now and noticed a small spelling mistake in the third PDw echo json where it says 'of' rather than 'off', but it's probably not worth correcting now as it will get changed again?

Thanks for #38 :)

Thank you, feel free to work on it as you like!

Regarding json files, the root json file (sub-01_suffix.json) should be containing some extra metadata fields (e.g. vendor and sequence specific tags). At least, this was the idea in the gdoc. Should we include this in the example datasets as well? @Gilles86 @KirstieJane maybe we can discuss this in the next meeting.

Hey folks - in #22 I think we're not following the derivatives proposal accurately.... (Here's the proposal: https://github.com/bids-standard/bids-specification/blob/derivatives/src/05-derivatives/01-introduction.md)

We should have a pipeline name for each of the derived folders, right?

I might be totally missing the mark here.... 😬

UPDATE - I've made an hmri pipeline folder in the PR to @lazaral's branch (lazaral#1)

This is related to #46

I fixed some of these issues in #38 - hopefully it is fairly up to date now, let me know if there's anything more I should change.
