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.*
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.
The dataset derivatives contain a number of files similar to the following:
There are three issues here:
