Hi Jony,

On further testing, Dennis and I found that neither of these methods really works right. Selecting rows and deleting them individually only works on available vials--the unavailable ones can't be selected. As for the import/replace option, it works as described IF there are new specimens in the import package. If we import a specimens.tsv with no rows, it will not remove any existing specimens, but it will blank all of their primary types. I should point out that we're using the study import feature for this, rather than the Import Data option you describe.

Thanks,
Peter
