Peter,

Thanks for the additional information. So officially at this time, there isn't a way to just delete the specimens directly beyond deleting vials and the replacement via the data import mentioned earlier.

That being said, there is a bug that I am going to file on the vials page issue where the unavailable ones are not selectable for deleting. That definitely shouldn't be behaving that way.

Regarding the zero row specimens.tsv file, was the file apart of a .specimen archive with labs.tsv and other tsv files? Also, when you did the Study Import, did you make sure that your zip file under /study/specimens/ only had a specimen_settings.xml file?

I found that if I created a study for the dummy specimens and verified the study was fine, I would export the study without the specimen data and then re-import that information back in as a new study with no specimen data (thereby allowing me to delete the previous study I made with the dummy specimen data). Have you tried this approach? It would definitely give you what you want - a study to test the dummy data against, confirming the study is good to use, then ending up with a fresh study with no specimen data.

Regards,

Jon
