Text Manipulation -> Concatenate datasets tail-to-head 

is the equivalent of cat :) 

btw galaxy also accepts gzipped files so you can upload it faster that way

Hi,

Can galaxy combine lots of data into a single file using "cat"? I have a 2GB sam type data, but I can't upload it by URL under my condition, so I want to spilt it into three files and upload it to galaxy and then combine it?

Thanks a lot!
