... Hi LIsa,
This is a very well-posed question! Thank you.
I contributed the MotifDb package a couple of years ago, but I am not intimate with the details of TF binding sites and their distribution. However, I notice that the JASPAR-CORE pwm for Myc is just 12 bases wide but TP53 is 20. In my ...

... The best course -- which we have discussed off-line, and which I believe seems promising to you -- is to switch to the new RCy3 package, currently submitted to Bioc, available on github, and for which we are actively soliciting testers.
If you will send me some more information I will try to reprod ...

The RefNet gerstein-2012 data interactions are from
http://archive.gersteinlab.org/proj/Hierarchy_Rewiring/PNAS_hier/Hs_Tr.txt
If other (and possibly more recent) interaction data sets are of compelling interest, let us know. The 4 which are built in to RefNet now ('native'; they liv ...

... Hi Anaïs,
Biomart changed the name of this attribute to simply "uniprot_swissprot" about the first of the year. We discovered this -- just as you did! -- and made the fix in PSICQUIC version 1.5.7.

... Another approach uses Steffen Durink's fine biomaRt package, a contribution to Bioconductor of many year's standing. In its simplest form just two lines of code gets you all the genes in one copy number region:
library(biomaRt)

... Hi Mark,
Thanks for keeping at this.
You have an out-of-date copy of RefNet. You need version 1.2.0. Please try this in your R session:
source("http://bioconductor.org/biocLite.R")
biocLite("RefNet")
suppressPackageStartupMessages(library(RefNet))
dir(system.file(package="RefNet", "apps")
Y ...

... In addressing some problems reported with using the RefNet package last week, I promised to follow up with an account of the RefNet/PSICQUIC shiny app.
