Hi all, I have recently run the HTA 2.0 annotation using the two packages affycoretools and hta20transcriptcluster.db as outlined in the post https://support.bioconductor.org/p/89308/. However, I have run into an error after running the rma() as follows:
> exprs_mainProbes<-getMainProbes(exprsgs, pd.hta.2.0) Error in switch(level, core = dbGetQuery(con, paste("select distinct core_mps.transcript_cluster_id, type from featureSet inner join core_mps", : EXPR must be a length 1 vector
Could you shed light into this problem? Thanks in advance.
