Bioc users - I am trying to set up the exonmap package and I have run into a problem that does not appear to be previously discussed in the mailing list. I have installed my local copy of Ensembl as well as the X-map database, as shown here. I can load exonmap library and the example data but I run into a MySQL error when I try to connect to the database. I am quite certain that I am connecting to the database because I was previously getting a different error message about user permissions. Can anyone offer any suggestions? Session info also included below. Thanks a lot. mysql> use homo_sapiens_core_45_36g Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> show tables; +---------------------------------------+ | Tables_in_homo_sapiens_core_45_36g | +---------------------------------------+ | alt_allele | | analysis | | analysis_description | | array | | arrayset | | assembly | | assembly_exception | [...] > data(exonmap) > pc.exonmap <- pc(x.rma,"group",c("a","b")) > sigs <- names(fc(pc.exonmap))[abs(fc(pc.exonmap)) > 1 & tt(pc.exonmap) < 1e-04] > length(sigs) [1] 31 > xmapDatabase("Human") done.
