In samWieczorek/DAPAR2: Tools for the Differential Analysis of Proteins Abundance with R

Sets the metacell dataframe for datasets which are from Proline software

Description

In the quantitative columns, a missing value is identified by no value rather than a value equal to 0.

In these datasets, the metacell info is computed from the 'PSM count' columns.

Conversion rules Initial conversion rules for proline |————–|—————–|—–| | Quanti | PSM count | Tag | |————–|—————–|—–| | == 0 | N.A. | whatever | 2.0 | | > 0 | > 0 | 1.1 | | > 0 | == 0 | 1.2 | | > 0 | unknown col | 1.0 | |————–|—————–|—–|
