External ID query

Dear colleagues

I have a quick query about the External ID column in the metadata file of the HMP2 project.
There are some IDs which have endings with _P. For example, CSM5FZ3N_P - however CSM5FZ3N is also present.

Are these completely different and independent samples ?

Can you please clarify ?

Looking forward to your kind response.

Best regards

Hi user,

ā€œ_Pā€ indicates that the samples are Paired-End samples. Therefore the other sample should be just the merged/single-end. Since the sample_id is the same, they are the same samples.
