Hi Dennis,

There's a couple of ways to delete specimens from a study. One option is to Import in new specimens to replace the dummy ones. The other option is to delete all the vials, which would remove the specimen records from the database.

To do a new import, just go to the Overview tab and click Manage Files. Then upload your specimens file and select the option to Import Data and then Import. If you select the Replace option, that will wipe out the dummy specimen data from earlier and replace it with your new specimen data.

If you want to delete the vials instead, make sure your Specimen Repository Type is setup as "Advanced (External) Specimen Repository" under the Manage Tab > Change Repository Type, then change set the Specimen Data to "Editable" and click Submit. Then you can go into the Specimen Data tab, view all specimens by Individual Vial and then select all and click the Delete option. This option is however the most cumbersome since you have to manually delete so many in one go, so I would advise using the file replacement option mentioned earlier.

Does this help?

Regards,

Jon
