MetaMS.runGC instant beginner error

Hello,

I'm fresh user of galaxy which i would like to use for GC-MS analysis. I convert the .D to MZxml and CDF which are both ok to upload but when i tried to excecute the older version i get this
An error occurred while running the tool toolshed.g2.bx.psu.edu/repos/yguitton/metams_rungc/metams_runGC/2.1.1.

Execution resulted in the following messages:

Fatal error: Exit code 1 ()

Error in matrix(unlist(lev), nrow = length(lev), byrow = TRUE) :
'data' must be of a vector type, was 'NULL'
Calls: -> as.data.frame -> matrix
In addition: Warning message:
In unzip(listArguments[["zipfile"]]) : error 1 in extracting from zip file
Execution halted
while importation was ok...

after transformation to xset.RDATA with XCMS I also get the following error....
3.0.0+metaMS1.24.0-galaxy0 .

Warning message:
replacing previous import 'xcms::plot' by 'graphics::plot' when loading 'CAMERA'
Note: you might want to set/adjust the 'sampclass' of the returned xcmSet object before proceeding with the analysis.
Error: You need more than 1 file to be able to run metaMS
Execution halted

Could anyone give me a piece of advice ?

Thank you very much,

Pierre-Yves

Hi Pierre-Yves,

For me the first error is linked to the fact that the zipfile entry is deprecated (we now use dataset collection). @gildaslecorguille is that right?

The second error seems to happen because you have only one cdf file in your Rdata and metaMS is not able to process only one file. Can you try with 3 files ?

Dear yann,

I have used the LCMS tools up to the Merge functionand then i have import the generated Rdata in metaMS (instead of mzML files) which works fine !

I've try to run it with three files unfortunatly it did not work because it's running three analysis separetly

Dear Pierre-Yves,
