Hi Cyril,

Jen's response includes the correct information about how symlinks are handled, and why. Changing the symlink underlying a dataset is not a great idea since it will cause the dataset's metadata to be incorrect and break Galaxy's concept of reproducibility. I would suggest that you utilize the library dataset versioning features to accomplish what you're trying to do.

Hope this helps, --nate

Hi all,

I created data libraries using options "Upload files from filesystem paths" and "Link to files without copying into Galaxy". It worked but I use symbolic links because my data are frequently updated

The problem is that Galaxy takes the real link (inside "external_filename" column in "dataset" table) and doesn't find the files when it is deleted.

For example, I uploaded a dataset for a data library without copying : /databank/uniprot/current/fasta/all.fasta -> /databank/uniprot/01_12_2012/fasta/all.fasta The real path is put in the database and it's a problem when it is deleted.

Is there a way for galaxy to take the symbolic link directly in the database instead of the real path.

Thanks in advance! Cheers, --
