Need some MACROS___ for top level files description

1

https://github.com/bids-standard/bids-specification/pull/1033/files reveals duplication of description for top level files in [src/03-modality-agnostic-files.md](https://github.com/bids-standard/bids-specification/pull/1033/files#diff-d9e3cba862521dd35f361952e6e6a7a4d20c5712af8715bd7d1ae38e057821ddR146) and [src/schema/objects/top_level_files.yaml](https://github.com/bids-standard/bids-specification/pull/1033/files#diff-c956e4a2decf6448a7e573bc50e93a4ea7a1af19f364b1818804a8005871f86bR24) thus begging for some `MACROS___` to just populate the .md with description from the schema.

How are subgroups to be dealt with? E.g. patients versus controls. Perhaps like this: group-patients group-controls where all subjections would be group-all _Originally posted by @robertoostenveld in https://github.com/_render_node/MDExOlB1bGxSZXF1ZXN0MjM4OTg3Njgy/timeline/more_items_

DICOM tags yaml vs md

4

a general comment related to https://github.com/bids-standard/bids-specification/pull/1021 - metadata.yaml is, in my mind, the BIDS set of definitions and therefore independent of DICOM - xxx.md is modality specific and can point...

Add support for multi-echo T1w scans

16

BIDS currently does not seem to support multi-echo anatomical T1w scans such as: sub-A00000909_ses-20110101_acq-mprage_run-01_echo-01_T1w.json sub-A00000909_ses-20110101_acq-mprage_run-01_echo-01_T1w.nii.gz It would be nice if this could be added in the future. See [this post...

How to handle lesion masks, including multi-session data?

2

This question came up in the context of how `smriprep` should handle multi-session data that has associated lesion masks (see https://github.com/poldracklab/smriprep/issues/58), but I think it raises a BIDS question too....

Complimentary to #174 although less concerned with placement and either lesions could be considered raw or derivative data (IMHO everything is derivative ;) ) ATM lesions are mentioned in two...

Allow 'object of objects' for 'ElectricalStimulationParameters'

10

I would like to propose to allow the data type `object of objects` additionally to `string` for `ElectricalStimulationParameters` in the `*ieeg.json` file ([see current specification](https://bids-specification.readthedocs.io/en/latest/04-modality-specific-files/04-intracranial-electroencephalography.html#sidecar-json-_ieegjson)). To give you an impression...
