BioSamples in ArrayExpress

The ArrayExpress submission system does not directly cater for the use of existing BioSamples accessions. Notify the ArrayExpress curators and explain that you wish to reuse existing BioSamples entries in your submission. They will provide further guidance.

GEO

Please add a new column in the SAMPLES section titled "BioSample ID" and include the SAM ID number for each sample. This will alert the curator handling your submission to link your records to each appropriate BioSample.

When you submit your data to GEO, please include in the notification email the fact that you have already generated BioSample IDs and have included them in the metadata spreadsheet.
