Hi, I am trying to use easyRNASeq to create count tables for DESeq analysis. I have about a hundred BAM files with their associated indexes, located in my file system and sorted in folders, on for each provider and in each one folder for each tissue. To not use to much space, I created simlinks from each of these BAM/BAI combo toward a single location so that easyRNASeq can read them all. When I try my command, I get this error: Error in easyRNASeq(filesDirectory = "/shares/data2/tmp01/inflammgen_t emp_transfer/htseq_datastore/RNASeq_datastore/RNASeq_comprehensive_cat alog/4.diff_ex_analysis/4.0.link2files/2013_10_29-16_00_07_NCBI_build3 7.from.2.2.phred_q_trimming_2013_10_24", : Index files (bai) are required. They are missing for the files: blablabla... But, the files are there :-( I removed the BAI symlinks and cp the real files to the same location and I get the same mistake... Is my idea of symlinking from the source the problem? Any idea appreciated ;-) Best regards Sylvain -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Sylvain Foisy, Ph. D.

Bonsoir Sylvain, I have never encountered that situation. I?ve tried to reproduce it but to no avail. Can you: 1) report your sessionInfo() to make sure you are using R-3.0.2 and easyRNASeq-1.8.2? 2) give me a glance of your symlink structure to see if my mockup recapitulated your case? 3) can you try to reproduce the following: Here is what I did to test easyRNASeq on what I guess was your symlink structure: a) first I created symlinks in my Desktop/tmp dir: lrwxr-xr-x 1 delhomme staff 71 Nov 26 17:02 ACACTG.bam -> /Users/de lhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/ACACTG.bam lrwxr-xr-x 1 delhomme staff 75 Nov 26 17:02 ACACTG.bam.bai -> /User s/delhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/ACACTG.bam.bai lrwxr-xr-x 1 delhomme staff 71 Nov 26 17:02 ACTAGC.bam -> /Users/de lhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/ACTAGC.bam lrwxr-xr-x 1 delhomme staff 75 Nov 26 17:02 ACTAGC.bam.bai -> /User s/delhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/ACTAGC.bam.bai lrwxr-xr-x 1 delhomme staff 71 Nov 26 17:02 ATGGCT.bam -> /Users/de lhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/ATGGCT.bam lrwxr-xr-x 1 delhomme staff 75 Nov 26 17:02 ATGGCT.bam.bai -> /User s/delhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/ATGGCT.bam.bai lrwxr-xr-x 1 delhomme staff 71 Nov 26 17:02 TTGCGA.bam -> /Users/de lhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/TTGCGA.bam lrwxr-xr-x 1 delhomme staff 75 Nov 26 17:02 TTGCGA.bam.bai -> /User s/delhomme/Library/R/3.0/library/RnaSeqTutorial/extdata/TTGCGA.bam.bai pointing to the example data package (RnaSeqTutorial) companion of easyRNASeq. b) then in R I ran: counts <- easyRNASeq(filesDirectory="Desktop/tmp", pattern="[A,C,T,G]{6}\\.bam$", readLength=30L,chr.sel="chr2L", organism="Dmelanogaster", annotationMethod="rda", annotationFile=system.file("data","gAnnot.rda",pa ckage="RnaSeqTutorial"), count="exons") and I got the expected count table. 4) btw, how did you create the links? As far as I remember, Windows does not create symlink in the same way a Unix system does, which is what I tried here.

Beats me? I?m really hitting in the dark here but: 1) Is there any possibility that you have circular symlinks, or symlink chains? I?m not sure how gracefully R would do with symlink chains. 2) Are there no permission issues on the bam/bai files or a subset of them? 3) Could it be that the symlink names are too long? That used to create problem in the distant past on some linux distro, but I have not seen it occurring in years.

I made it work when I am in the original location (a single BAM/BAI combo) and it works so the hypothesis of long paths might be it... I'll see what I can do to rename my stuff with shorter names.
