hi,
i can reproduce what Jianhong says, i noticed it earlier this week but
didn't mention because we all know devel is a moving target and so on,
but since this has been raised now i'll report what i'm getting.
so, this is for Jianhong, if you downgrade the following packages to
these particular versions:
Biostrings_2.31.3.tar.gz
GenomicRanges_1.15.15.tar.gz
IRanges_1.21.13.tar.gz
XVector_0.3.2.tar.gz
you'll be all fine, unless you need some functionality of later versions
of them, here is the test with the session information:
suppressPackageStartupMessages(library(TxDb.Hsapiens.UCSC.hg19.knownGene))
Warning messages:
1: multiple methods tables found for ‘rname’
2: multiple methods tables found for ‘rname<-’
3: multiple methods tables found for ‘cigar’
4: multiple methods tables found for ‘qwidth’
5: multiple methods tables found for ‘introns’
system.time(txbygene <- transcriptsBy(TxDb.Hsapiens.UCSC.hg19.knownGene,
"gene"))

however, if you go to the bleeding edge of devel BioC:
suppressPackageStartupMessages(library(TxDb.Hsapiens.UCSC.hg19.knownGene))
system.time(txbygene <- transcriptsBy(TxDb.Hsapiens.UCSC.hg19.knownGene,
"gene"))
the previous call never ends until you press CTRL+C:

In my case, looks like never end.
I need to check my R first.

Hi Jianhong,
According to my timings, it's a little bit slower than exonsBy() but
not that much. It has to do a little bit more work too as the introns
are not explicitly stored in the SQLite db (the exons are) but are
inferred from the exons and transcript boundaries.
So intronsByTranscript() has to retrieve all the exons + all the
transcripts from the db.
intronsByTranscript():
library(TxDb.Hsapiens.UCSC.hg19.knownGene)
system.time(introns<-
intronsByTranscript(TxDb.Hsapiens.UCSC.hg19.knownGene))
# user system elapsed
# 9.165 0.076 9.263
system.time(introns<-
intronsByTranscript(TxDb.Hsapiens.UCSC.hg19.knownGene))
# user system elapsed
# 4.824 0.064 4.896
exonsBy():
library(TxDb.Hsapiens.UCSC.hg19.knownGene)
system.time(exons<- exonsBy(TxDb.Hsapiens.UCSC.hg19.knownGene))
# user system elapsed
# 7.720 0.072 7.812
system.time(exons<- exonsBy(TxDb.Hsapiens.UCSC.hg19.knownGene))
# user system elapsed
# 4.229 0.028 4.265
transcripts():
library(TxDb.Hsapiens.UCSC.hg19.knownGene)
system.time(tx<- transcripts(TxDb.Hsapiens.UCSC.hg19.knownGene))
# user system elapsed
# 1.424 0.008 1.436
system.time(tx<- transcripts(TxDb.Hsapiens.UCSC.hg19.knownGene))
# user system elapsed
# 0.776 0.012 0.790
Less than 10 sec. to retrieve all the exons and transcripts from disk
and compute the 659327 introns. It's actually not that bad.
Cheers,
H.

Dear all,
When I try to use intronsByTranscript to get introns for hg19 known
genes, I found it is unacceptable slow. Does any body has the same
problem?
My code:
library(GenomicFeatures)
library(TxDb.Hsapiens.UCSC.hg19.knownGene)
introns<- intronsByTranscript(TxDb.Hsapiens.UCSC.hg19.knownGene)
