From a98160aed1256f1b2ffe4b20a82e26b01f57d90c Mon Sep 17 00:00:00 2001 From: Yaroslav Halchenko Date: Thu, 24 Aug 2023 13:57:28 -0400 Subject: [PATCH] Allow for "echo" entity to be used with T1w (and other "anat" nonparametric) sequences (#1570) Closes #654 https://github.com/bids-standard/bids-specification/issues/654 provides more of discussion with a number of people bringing up the use cases which keep coming about. As EchoTime is a recommended sidecar file metadata field for any file of 'mri' modality, I decided that it would only be logical for at least existing use cases (T1w) and possibly other cases (to not overspecify T1w) to simply allow for "echo" entity to be used if so necessary to distignuish two files while they do remain of that weighting (e.g. T1w) given the EchoTime values. --- src/schema/rules/files/raw/anat.yaml | 1 + 1 file changed, 1 insertion(+) diff --git a/src/schema/rules/files/raw/anat.yaml b/src/schema/rules/files/raw/anat.yaml index 2e534a2817..3e026107f4 100644 --- a/src/schema/rules/files/raw/anat.yaml +++ b/src/schema/rules/files/raw/anat.yaml @@ -27,6 +27,7 @@ nonparametric: ceagent: optional reconstruction: optional run: optional + echo: optional part: optional parametric:
