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!
