Re: [galaxy-dev] about sequencing requests

Davide;

What are "Data Libraries" and "Folder" in sample request and grid information in sample request edit page?

Those specify the Data Library and Folder where sequencing results should be returned. The backend code uses these to semi-automatically transfer files back into Galaxy from the sequencer. If you haven't used Data Libraries previously, Admin -> Manage data libraries is the place to get started. Brad
