By "imported", do you mean imported from / to a history? If so, then the Bam file has previously been uploaded, at which time the associated index was created. Importing in this case just means another pointer to the disk file is created.

Are bam indexes (.bai) automagically created when a bam file is imported (either from or into a library)? If not, how can I do it?
