Hi, Two things:
1. You mistakenly posted this to the R-help list, when you should have (and probably meant to) send to the bioconductor list. You might want to repost there if you can't figure out the problem. 2. I just tried your query with 4 transcript IDs (one of them was a duplicate) and it worked fine. Maybe the error you are receiving is actually informative of what your problem is: > Error in value[[3L]](cond) : > Â Request to BioMart web service failed. Verify if you are still connected to > the internet. Â Alternatively the BioMart web service is temporarily down. and for some reason you're just having a problem talking to the biomart service itself ... Why not try your query with a small number of ensemble transcript id's to see if that'll work? -steve -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
