Hi, I don't undestand how to use the tool "Stitch MAF blocks". I update a small bed file and now I need to run this tool, I don't understand the next step. I'm searching for Novel Linc in some RNA-seq data and I found the lncRscan tool (http://code.google.com/p/lncrscan/wiki/example) and now I have to use "Stitch MAF blocks". The point is: I update the bed file, I select Fetch Alignments -> Stitch MAF blocks, and then I can do nothing, I can only choose among "locally cached alignments" and "alignments in your history". But MAF type/MAF file remain empty, in any case. Can someone be so gentle to solve my problem? Do I need to download a MAF file? Is it normally on Galaxy server, but now it is down? How can I produce a MAF file selecting only some species (29 mammals)? Thank you really much. Jennifer
