Comment: C: featureCounts error : SAM_pairer_iterate_tags
... From the error message in your post, it is a "general format error" encountered by featureCounts. In other words, featureCounts couldn't correctly parse the current alignment record in the BAM file. I generated a BAM file myself using `rsem-tbam2bgam` but featureCounts ran correctly on it. Can you ...

Comment: C: Rsubread- feature counts
... Thanks for the details. I noticed that you ran propmapped() on the BAM files, then gave the return value from propmapped() directly to featureCounts(). As you may have noticed, the return value from propmapped() is a data.frame object, and featureCounts cannot take a data.frame as the argument for i ...

Answer: C: GZIP ERROR:-2 using featureCounts (Subread)
... Hi Gwenael, The "GZIP ERROR:-2" message sounds like an old bug in featureCounts. Which version of featureCounts did you use? If it was not the latest version (v1.6.3), you can try our latest version, which is available on   https://sourceforge.net/projects/subread/files/subread-1.6.3/ since this ...

Comment: C: makeTxDbFromGFF drops genes which have multiple chromosome locations. (with iGen
... I'm facing the same problem and I found that the makeTxDbFromGFF() function already dropped the exons if they span multiple chromosomes and/or multiple strands. I built a GTF file that contains only four exons from one gene, but from different strands of chr1. The makeTxDbFromGFF() function gave wa ...

Comment: C: Rsubread install fails, "unable to load shared object Rsubread.so"
... Thanks for the detailed explanation! Yes, I can now reproduce the error by adding "-O 0" to the compiler parameters. It is a little surprising to see that an optimisation option can change the legitimate behaviour of the compiler. I have removed this keyword from my codes.  ...

Answer: A: Rsubread install fails, "unable to load shared object Rsubread.so"
... I understand that the "inline" keyword instructs the compiler to embed the function into all its callers, and modern compilers are smarter to automatically make the decision, leaving this keyword obsolete. However, it should be harmless when you build a shared object from the codes including inline ...

Comment: C: Rsubread featureCounts with byReadGroup
... Thanks! I've downloaded the data, and found that featureCounts had a bug in the routine for fixing the BAM format. It did not keep the read group names when fixing the BAM files from Picard or STAR.  This bug has been fixed. The next released version should work on your BAM files. Cheers, Yang ...

Comment: C: Rsubread featureCounts with byReadGroup
... It still works when I converted the SAM file to BAM by using Picard (SortSam). Is it possible if you can send us the BAM file you're using?  Cheers, Yang # /picard-tools-2.9.4/bin/SortSam I=user-RG.bam o=user-RG-Picard.bam SO=coordinate > x<-featureCounts(c('user-RG.bam','user-RG-Picar ...

Answer: A: Rsubread featureCounts with byReadGroup
... Hi Ge Tan, I used Rsubread_1.26.1 to assign the lines you provided, and the read groups were correctly treated by featureCounts: x<-featureCounts(c('user-RG.bam','user-RG.sam') , annot.inbuilt = "hg19", byReadGroup = T) NCBI RefSeq annotation for hg19 (build 37.2) is used. //================= ...
