Dear all, I'm trying to enable bigwig support in Galaxy. Besides the sniff section which is probably not working, I'm trying to enable at least the visualization on a UCSC mirror. I see that galaxy link to display includes this hgt.customText http://host001.instruments.ifom-ieo-campus.it:8080/display_application/e00d4... which contains the track definition: track type=bigWig name="Pu1_100219.bw" bigDataUrl=http://host001.instruments.ifom-ieo-campus.it:8080/display_application/e00d4... db=hg18 Unfortunately the genome browser (a local mirror) says: Error udc couldn't read 4 bytes from http://host001.instruments.ifom-ieo-campus.it:8080/display_application/e00d4..., did read 0 I've tried to fetch the bigwig file in bigDataUrl link with wget and I'm able to reach it. Needless to say, the bigwig file is a proper one, I've tried to load it from another location and it can be displayed. At this point I don't know how to debug it... @UCSC people: when am I supposed to get that error? Which conditions raise it? @Galaxy people: since the link is valid, why I cannot present it to UCSC?
