Hi All,
I am analyzing some ChIP seq data using DESeq, reads have all been
aligned and are in BAM format.
"aligned" in a names character vector containing the names of the bam
files.
I'm trying to use the Genominator function importFromAlignedReads to
read in the aligned data, but I get an error regarding the system.time
function:
> aligned
20417.6.bam 2041T.6.bam 305AG.8.bam 305D0.8.bam
"20417.6.bam" "2041T.6.bam" "305AG.8.bam" "305D0.8.bam"
> chroms
[1] "chr1" "chr2" "chr3" "chr4" "chr5" "chr6" "chr7" "chr8"
"chr9"
[10] "chr10" "chr11" "chr12" "chr13" "chr14" "chr15" "chr16" "chr17"
"chr18"
[19] "chr19" "chr20" "chr21" "chrX" "chrY" "chrM"
> eData <- importFromAlignedReads(aligned, chrMap=chroms,
dbFilename='test.db', tablename='raw', type="BAM", verbose=FALSE)
Error in system.time(exp) :
Unable to write the table, delete table or specify overwrite.
In addition: Warning message:
In value[[3L]](cond) :
RS-DBI driver: (error in statement: near "20417.6": syntax error)
Timing stopped at: 0.076 0 0.081
Timing stopped at: 12.851 0.74 13.631
Any idea what might be wrong, anyone seem a similar issue earlier?
Seems to be the second call to system.time within
importFromAlignedReads that breaks the function.
