Hello, I am dealing with a BACs microarray, but the annotation I have is from an old version of the human genome. Could anyone suggest some ways of updating the information to hg19? I would initially like the positional information, but also want gene(s) the BAC covers and whether the BAC covers the whole gene or whether it is at the front or back. For each BAC I have a clone name e.g. RP11-172L12 and a ChoriID N0172L12.

You could use the table browser to get the data that you want or just download the whole table. A workflow of rtracklayer track downloads into IRanges objects of one type or another for genes and bac-ends would allow you to get the overlap of bac-ends with genes; I don't have details at hand, but the data sources are easily available.

That's great, many thanks for that. The only problem I am having is that some of the clones do not come up in the bacEndPairs table, for example RP11-363L4 or CTD-2001A18. When I search for these in Ensembl they sometimes are there as a sequence, but sometimes not. Any ideas? The non-matching clones are about two thirds of the set.

Do you have the original design file with genomic locations? If so, use the UCSC liftover tool to go from the old genome to the genome of your choice. Have the arrays been used in a published experiment? If so, the design file may be available via NCBI GEO or ArrayExpress.

Hello, Sorry to come back onto this, but I can't get Lift Genome Annotations (http://genome.ucsc.edu/cgi-bin/hgLiftOver) to work whatever I do. Has anyone else had any success with this tool? I always get "#Deleted in new" for all the Clone's positions. In fact, even if I try a test like "Chr1:100000-100001", I get the same error. Apologies for needing my hand held on this one.
