TableInfo: collection_ptm.tsv - nih-cfde/published-documentation GitHub Wiki

Association between a collection and a post-translational modification (PTM) term

For collections with PTM metadata, this table will have one row for each PTM associated with each such collection.

All fields are required: this table can be empty (header-row only), but any non-header rows must leave no fields blank.

Some examples:

• If you don't have any collections associated with PTMs, this table should be left empty.
• If you have exactly one PTM associated with each collection, this table will have as many rows as collection.tsv.
• If you have five PTMs associated with each collection, this table will have five times as many rows as collection.tsv.
• If some but not all of your collections are associated with one or more PTMs, this table will contain one row for each PTM assigned to each such collection (and the resulting row count will not have any obvious relationship to the number of rows in collection.tsv, which is both expected and fine in such a case).

Field	Field Description	Required?	Field Value Type	Extra Info
collection_id_namespace	Identifier namespace for this collection [part 1 of 3-component composite primary key]	Required	string	This will be the value of id_namespace in the row in collection.tsv corresponding to the collection referenced in this row. If your program has not registered multiple CFDE identifier namespaces, this will be exactly the same value for all rows.
collection_local_id	The ID of this collection [part 2 of 3-component composite primary key]	Required	string	This will be the value of local_id in the row in collection.tsv corresponding to the collection referenced in this row.
ptm	A valid PTM ID term [part 3 of 3-component composite primary key]. This is also a foreign key to the table ptm.tsv [id column there].	Required	string
