Hi List,

Our tools require an array of input files and also produce an array of files.  This seems as a pretty standard task, but unfortunately Galaxy doesn’t support this yet.

I wonder if somebody has already implemented this kind of ‘file array’ data type? 

I.e. the user selects a local directory and uploads all files as a single dataset. Even better if the user could specify a regular expression for file selection.

I know that there are other options, i.e. taring the files or using composite data type, but they don’t seem natural.

Any hints?
