Annotating sample accessions for existing proteomeXchange datasets

[ypriverol]

One of the most important use cases for this repository is to re-annotate existing datasets in ProteomeXchange. In those cases in the source name - the sample accession - I recommend using the ProteomeXchange accession as the prefix for every sample. Something like:

PXD{XXXXXX}-Sample-{Sample number} For example: PXD003452-Sample-5

This is convenient because when datasets get shared in other resources, users can associated easily the sample to the given ProteomeXchange project.
