Hello,

I am working with Drosophila melanogaster dm6 and I wish to use a package that requires both BSgenome.Dmelanogaster.UCSC.dm6 and BSgenome.Dmelanogaster.UCSC.dm6.masked. I could download the former one but I need to forge the second.

I am facing an error message while installing the genome masked package at the R CMD CHECK step. I was thinking that maybe the error could be related to many contigs sequences present in the twoBit file. However, this doesn't seem to be a problem while forging the genome with bare sequences. What did I miss(understand) in the manual?

My seed file:

Package: BSgenome.Dmelanogaster.UCSC.dm6.masked
Title: Full masked genome sequences for Drosophila melanogaster (UCSC version dm6)
Description: Full genome sequences for Drosophila melanogaster (Fly) as provided by UCSC (dm6, Aug. 2014) and stored in Biostrings objects.The sequences are the same as in BSgenome.Dmelanogaster.UCSC.dm6, except that each of them has the 4 following masks on top: (1) the mask of assembly gaps (AGAPS mask), (2) the mask of intra-contig ambiguities (AMB mask), (3) the mask of repeats from RepeatMasker (RM mask), and (4) the mask of repeats from Tandem Repeats Finder (TRF mask). Only the AGAPS and AMB masks are "active" by default.
Version: 1.4.2
RefPkgname: BSgenome.Dmelanogaster.UCSC.dm6
source_url: http://hgdownload.cse.ucsc.edu/goldenPath/dm6/bigZips/
organism_biocview: Drosophila_melanogaster
nmask_per_seq: 3
SrcDataFiles: AGAPS masks: dm6.agp.gz from http://hgdownload.cse.ucsc.edu/goldenPath/dm6/bigZips/
    RM masks: dm6.fa.out.gz from http://hgdownload.cse.ucsc.edu/goldenPath/dm6/bigZips/
    TRF masks: dm6.trf.bed.gz from http://hgdownload.cse.ucsc.edu/goldenPath/dm6/bigZips/
#PkgExamples: genome$chr2L  # a MaskedDNAString object!
## To get rid of the masks altogether:
#unmasked(genome$chr2L)  # same as BSgenome.Dmelanogaster.UCSC.dm6$chr2L
masks_srcdir: .
AGAPSfiles_type: agp
AGAPSfiles_name: dm6.agp
RMfiles_name: dm6.fa.out
TRFfiles_name: dm6.trf.bed

I have to precise that I used the agp file type despite the fact that this file is coming from the UCSC site.

Warning messages:

same warnings for "chr2R", "chr3L",  "chr3R",  "chr4",  "chrM",  "chrX" and "chrY"

I don't know what to modify in the seed file to solve this warnings, which may have an effect on the following step:

R CMD build BSgenome.Dmelanogaster.UCSC.dm6.masked
R CMD check BSgenome.Dmelanogaster.UCSC.dm6.masked_1.4.2.tar.gz
return

the 00install.out file contains:
