Hi Paolo,
FYI 3 days ago I contacted Gabriele Sale (maintainer of graphite
and co-author of clipper) about this. See below.
Cheers,
H.
-------------------------------------------------------------------
Hi Gabriele,
A recent update to the graphite package introduced the following
change:
library(graphite)
kegg <- pathways("hsapiens", "kegg")
graph <- convertIdentifiers(kegg[["Chronic myeloid leukemia"]], "entrez")
graph <- pathwayGraph(graph)
genes <- nodes(graph)
head(genes)
# [1] "ENTREZID:10000" "ENTREZID:1019" "ENTREZID:1021"
# [4] "ENTREZID:1026" "ENTREZID:1029" "ENTREZID:1147"
This is with version 1.23.4 of the package. With version
1.23.3, the same commands gave:
head(genes)
# [1] "10000" "1019" "1021" "1026" "1029" "1147"
Was this change intended?
Note that this change breaks the clipper package for which you are
a co-author:
https://bioconductor.org/checkResults/3.6/bioc-LATEST/clipper/
Also please note that the DEGraph package is currently broken
because it depends on NCIgraph which itself depends on RCytoscape
which is currently broken and deprecated. Unfortunately this breaks
the graphite vignette (which seems to use DEGraph):
https://bioconductor.org/checkResults/3.6/bioc-LATEST/graphite/
The DEGraph and NCIgraph authors have been contacted and are aware
of the situation but have not been able to fix their package yet.
If they cannot fix it in time for the upcoming BioC 3.6 release,
their package will be considered as candidate for deprecation in
Bioc 3.7. So at this point I would strongly suggest that you remove
graphite's dependency on DEGraph.
Please address these issues at your earliest convenience.
The next Bioconductor release is coming soon (scheduled for end
of October) and all Bioconductor packages are expected to be
fixed before Tuesday October 24.
See https://bioconductor.org/developers/release-schedule/ for
our release schedule.
Don't hesitate to ask on the bioc-devel mailing list if you have
any questions or concerns about this.
Thanks for your contribution to Bioconductor!
Regards,
H.
