Entity following suffix, with value field containing minuses and key unknown to BIDS.

[TheChymera]

The dataset derivatives contain a number of files similar to the following:

derivatives/sub-I48/ses-SPIM/micr/manual-annotation/sub-I48_ses-SPIM_sample-BrocaAreaS05_stain-NeuN_SPIM_pos-88-5069-1709.tif

There are three issues here:

1. nothing should follow the suffix, other than an extension, which is delimited from it via a period. _SPIM is a suffix, and the only BIDS-valid form a SPIM filename can take is *_SPIM.*
2. the substring pos-88-5069-1709 (known to BIDS as an entity) should only contain one minus, which is used to separate the entity name (or key) from the value. The value should contain only alphanumeric characters. 88-5069-1709 is wrong, but e.g. 8850691709 or 88a5069a1709 would be correct.
3. the pos entity is not known to BIDS.

Again, unsure how to correct this.
