My name is Sam, a grad student at the University of Missouri, and I am having trouble importing my .gtf file using the rtracklayer function import(). My gtf file seems to have the 9 columns specified by the gtf format when looking at it in a text editor, but on import I have 9 columns labeled as "X1.", "X2",...,"X9." nearly all of the entries are NA. In X1. there are 817 "1\" entries (of 474351), in X2. there are 534 "2\" and so on. The .gtf file was downloaded from http://tophat.cbcb.umd.edu/igenomes.html Arabidopsis NCBI TAIR10 release, using the genes.gtf file generated after opening the .tar.gz. I import my file by myGTF <- "path/to/file.gtf" newGTF <- import(myGTF, asRangedData = FALSE) The way I read the import.gff manual, the .gtf extension will tell the function how to parse the file with out specifying version parameter. I am trying to follow the summarizeOverlaps() method of generating read counts from the GenomicRanges packages for differential expression using DESeq. Does anyone know what has happened, or more generally what can I do to import my file? -- output of sessionInfo(): > sessionInfo() R version 2.15.0 (2012-03-30) Platform: x86_64-unknown-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=C LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] DESeq_1.8.3 locfit_1.5-8 Biobase_2.16.0 [4] rtracklayer_1.16.3 Rsamtools_1.8.6 Biostrings_2.24.1 [7] GenomicRanges_1.8.6 IRanges_1.14.3 BiocGenerics_0.2.0 loaded via a namespace (and not attached): [1] annotate_1.34.0 AnnotationDbi_1.18.0 bitops_1.0-4.1 [4] BSgenome_1.24.0 DBI_0.2-5 genefilter_1.38.0 [7] geneplotter_1.34.0 grid_2.15.0 lattice_0.20-6 [10] RColorBrewer_1.0-5 RCurl_1.91-1 RSQLite_0.11.1 [13] splines_2.15.0 stats4_2.15.0 survival_2.36-14 [16] tools_2.15.0 XML_3.9-4 xtable_1.7-0 [19] zlibbioc_1.2.0 -- Sent via the guest posting facility at bioconductor.org.

Thanks for the report. The issue is that there are semi-colons embedded in the gene names. This is perfectly valid, but rtracklayer is not smart enough to check for quote escapes. I'll look into fixing this.

Michael, Are the gene names you are referring to the ones in the last column? gene_id "ATMG00010"; transcript_id "ATMG00010.1"; exon_number "1"; gene_name "ORF153A"; ... What is an appropriate deliminator? Can I just use a perl substitution for the new deliminator?

I just need to fix rtracklayer so that it handles the quoting. I'll work on it now.

Should be resolved as of 1.19.12. Had to rewrite the attribute parser though, so there could be breakage elsewhere.
