We have large files that cannot be uploaded using the "file upload" command and instead would need to be uploaded using a URL. Unfortunately, we are using a "local" install on a non-local machine, so setting up an FTP server on this machine is a security issue. The files are located on this computer already anyhow, and Galaxy would simply be copying from one folder to another in order to perform the "get data" step. Is there a simple way to have a "pointer" of some sort such that galaxy knows where this file is and: 1) Would not have to copy it and could simply refer to the file location. 2) Could perform data analysis steps on this file and push the output to the usual location (not the location of the data files). Any help would be greatly appreciated. Thanks.

Hi Greg, Upload your files to a Galaxy data library using a combination of "Upload files from filesystem paths" without copying data into Galaxy's default data store.

Thank you very much for your help with this - we got that settled. One other question...we are importing sorted, indexed bam files into a galaxy data library and we are not having galaxy copy over the files (they are large) but rather just setting up galaxy such that it points to the relevant directory. We noticed that the file (160 GB in size) is taking a long time to import considering all it should be doing is creating a link. When we examined processes that are running, we noticed that samtools is running. From searching around a bit, it seems that Galaxy does this in order to groom the bam file (sort/index) and ensure that it is in the format necessary for galaxy to be able to interpret it. Is there any way around this? We did the sorting and indexing prior to import and it's taking quite a while to perform an unnecessary function. Thanks.

Hi Greg, Even though you are not copying the data into Galaxy's default data store, Galaxy determines and stores certain metadata for each of the data files to which you are linking. One of the types of metadata defined for the Bam datatypes is it's index, which is created by a call to samtools. Unfortunately there is really no way around this because Galaxy requires the index file to be in a correct state, and I believe the test to determine correctness is at least as intensive as generating the index in the first place. It's been a while since I was involved in this (specifically setting metadata for bam files using samtools), so perhaps samtools has been recently improved in this regard. if so, I'll look to others to let me know I'm now "outdated" in my understanding of this. If we need to update samtools used by the Galaxy code to take advantage of newer features, we can certainly do so. Greg Von Kuster

Thanks again for the feedback...one final (hopefully) thing....as I mentioned in first e-mail, we are trying to add a large (~170 GB) BAM file to a library with just a link to the file (no copying). After at least an hour of working, I get the error message "Unable to finish job, tool error". Any thoughts as to how I can fix this? Thanks.
