Comment: C: FeatureCounts counts wrongly when quantifying mixed paired and unpaired reads
... One reason for featureCounts not allowing the mixture of single-end and paired-end reads in one SAM/BAM file is that the counts of single reads shouldn't be added to the counts of fragments because they are different things. A normal read aligner reports unpaired read mapping results as paired-end ...

Comment: C: FeatureCounts counts wrongly when quantifying mixed paired and unpaired reads
... Hi Kristoffer, I'm not sure what is in the `paired_and_unpaired.bam` file. Does it contain both single-end and paired-end reads? You can figure it out by running `$ samtools view paired_and_unpaired.bam | awk 'and($2, 1) == 1' | wc -l` and `$ samtools view paired_and_unpaired.bam | awk 'and($2, ...

Answer: A: Index genome generation with Subread for colorspace data
... Hi Gökberk, I downloaded the 5.0 version of the Macaca Fascicularis genome from Ensembl (the top-level sequences, 867 MB in gzipped format). I then ran the index builder in Subread-1.6.4 with the same arguments as you used. The index was built in 45 minutes with no error, and the "scan uninformativ ...

Comment: C: featureCounts error : SAM_pairer_iterate_tags
... Thanks, Leo. I've received the BAM file, and featureCounts (v.1.6.3) ran smoothly on it, with the read-count table generated. I've sent you some further suggestions to try, and if everything just doesn't work, I hope to build a special version of featureCounts with running details written into logs, ...

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 ...
