Hi all,
I'm new to RNA-seq analysis. And I'm now trying to use R to visualize
the Galaxy data. I'm using the cummeRbund to deal with the data from
cuffdiff in Galaxy.
Here is the codes I've run:
> cuff= readCufflinks (dbFile = "output_database", geneFPKM =
"gene_FPKM_tracking", geneDiff =
"gene_differential_expression_testing", isoformFPKM =
"transcript_FPKM_tracking",isoformDiff =
"transcript_differential_expression_testing", TSSFPKM =
"TSS_groups_FPKM_tracking", TSSDiff =
"TSS_groups_differential_expression_testing", CDSFPKM =
"CDS_FPKM_tracking", CDSExpDiff =
"CDS_FPKM_differential_expression_testing", CDSDiff =
"CDS_overloading_diffential_expression_testing", promoterFile =
"promoters_differential_expression_testing", splicingFile =
"splicing_differential_expression_testing", rebuild = T)
> cuff
CuffSet instance with:
2 samples
26 genes
44 isoforms
36 TSS
0 CDS
26 promoters
36 splicing
0 relCDS
> disp<-dispersionPlot(genes(cuff))
> disp
Error in `$<-.data.frame`(`*tmp*`, "SCALE_X", value = 1L) :
replacement has 1 rows, data has 0
In addition: Warning message:
In max(panels$ROW) : no non-missing arguments to max; returning -Inf
Does any one know why there's error? My cummeRbund is the latest
version, R is 2.15.3, and cuffdiff v1.3.0.
I've tried to search the internet for solutions but apparently it's
not a problem that people discussed much.
Also, the original files were generated from Galaxy, and the three CDS
files were empty. Would that cause the problem? If so, how should I
solve it? I used reference sequence as the fasta file, and the gtf
annotation file from Ensembl.
Thank you very much in advance!!!
Nancy
