Filter samples from mapping file (not a feature table)

Hello,

I am trying to split my mapping file to only have a specific subset for longitudinal analysis. I can only find information on filtering feature tables. Can some please let me know how to do this? Thank you!

Best,
Victoria

Hi @Victoria_Ruiz,

Are you referring to your metadata file with the sample information? If so, then you can simply just edit that using your tool of choice for example with excel.

In general, most actions in :qiime2: do not need the sample metadata file to be filtered — you can just use the same big original metadata file and use it with filtered feature tables so long as it is a superset of the samples.

I say in general because there may be exceptions, particularly for 3rd-party plugins...
