I am getting the following error upon execution of the following instruction during the first loop iteration: > for(j in 1:nrow(gene.map)) { + seq <- "" + seq = getSequence(id=gene.map[j,"ensembl_gene_id"],type="ensembl_gen e_id",seqType="3utr",mart=hmart) + print(seq) + } Error in getBM(c(seqType, type), filters = type, values = id, mart = mart, : Query ERROR: caught BioMart::Exception: non-BioMart die(): DBD::mysql::st execute failed: File './sequence_mart_54/hsapiens_genomic_sequence__dna_chunks__main.MYD' not found (Errcode: 27) at /srv/biomart_server/biomart.org/biomart- perl/lib/BioMart/Dataset/GenomicSequence/DNAAdaptor.pm line 209. I have attached the script that triggers the error. Can anyone help me understand the cause of such a message so that I can try and find a work-around ? I will emcompass the exception with a "try" instruction so that the script won't die .... Why am I coming across such an exception ? Thank you very much in advance. Maura e tutti i telefonini TIM!
