Hi all, I have just installed R version 2.8.0 and the updated to the new Bioconductor-version 2.3 packages. I have used SQLForge to create a new annotation package for the Arabidopsis Chip (using a custom-made annotation package); I have successfully installed the new package, but the loading requires a chrlengths-table, which does not exist for the Arabidopsis base-level annotation database (as discussed in the thread "Arabidopsis chromosome location mappings"). So I got the following error: >library(TinesATH1b.db) Loading required package: DBI Error in sqliteExecStatement(con, statement, bind.data) : RS-DBI driver: (error in statement: no such table: chrlengths) Error : .onLoad failed in 'loadNamespace' for 'TinesATH1b.db' Error: package/namespace load failed for 'TinesATH1b.db' Is there a way around the problem? Or is it necessary to include a chrlengths-annotation in the Arabidopsis base-level package? Or is the error not really related to the missing chrlengths-table? Thanks a million for further help!
