Hi Jeremy,
Thanks for your quick response.
I'll try switching from using 'tools/plotting/r_wrapper.sh' from Galaxy distribution, to my own wrapper using python, so I can use your advice.
I still wonder if this is the best way to run R's scripts? I would have thought there would be a simpler option. I wonder if "r_wrapper.sh" could be improved to absorb stderr messages, I would guess Bash has these capabilities.
Thanks, Carlos

Carlos,
You'll want to have your wrapper collect output to stderr and report only if the tool fails. See the Cufflinks/compare/diff wrappers for examples of how this can be done.
Good luck, J.

Hi all,
I'm working on integrating cummeRbund[1] into Galaxy. This is a very helpful tool for analysis and visualization of cuffdiff output.
My problem is any text output from running R code, puts the galaxy output in error state. Even if everything is working correctly and the outputs are generated as intended. I tried this code from 'tools/plotting/xy_plot.xml': ## Setup R error handling to go to stderr options( show.error.messages=F, error = function () { cat( geterrmessage(), file=stderr() ); q( "no", 1, F ) } )
But it didn't help. Even for loading the library I had to go with: suppressPackageStartupMessages(library("cummeRbund"))
Nothing else would work. Now the tool is outputting some messages while running R functions, which is putting the output in galaxy in error state. I'm thinking about asking the upstream developer to provide a way to run the functions in the library in 'quite' mode. Is there any other option?
Right now I'm using the path of creating a R script in the XML file and using r_wrapper.sh to run it. I tried first with rpy, as it would give me more freedom, but cummeRbund use ggplot2 which seems to be supported only on rpy2.
