"Annotations" is a general term for platforms (e.g. mRNA platforms) and other ancillary data that needs to be loaded before the experiment data for a certain high dimensional type. The annotation is generally not specific to a certain dataset, and can be shared between two or more similar datasets.
For historical reasons, parameter files named
annotation.params refer to mRNA platforms. But you should prefer to use the
mrna_annotation.params name for new files instead.
PLATFORMMandatory. The identifier for the annotation. The name is perhaps too specific. It should generally correspond to the name of the parent directory of the parameters file. However, unlike
STUDY_ID, it is not inferred.
TITLEMandatory. A human readable title for the annotation.
ANNOTATIONS_FILEMandatory. Either a full path to a TSV file or the name of TSV file under a directory that is a sibling of the parameters file and has the same name as the parameters file, minus its extension.
ORGANISMDefault: Homo Sapiens. The scientific name of the species the annotation is associated with.
GENOME_RELEASEMandatory if platform contains chromosomal region information. The genome build if applicable (e.g.
