Ca bloque sur la brique xcmsfindChromPeak Merger J’ai le message “his job was terminated because it used more memory than it was allocated.” Dataset Error An error occurred while running the tool **toolshed.g2.bx.psu.edu/repos/lecorguille/xcms\_merge/xcms\_merge/3.6.1+galaxy0**. Est-ce que vous pourriez regarder quel pourrait être le problème svp ? Merci d’avance pour votre aide Bonne journée Florence ---

Hi, my XCMS workflow applicated to a list with 383 items doesn't work and became red at the step xset.merged.RData. The message is " Job was terminated because it used more memory than it was allocated" I am stopped their just before the Group and I can't go ahead anymore ... The same worklow with a list of 92 items worked without any trouble to the end of the process. Could you help me please ? I have to process this study and the next bigger one wich will contain arount 900 items. Regards Florence ---

Hi Florence, It seems your problem is linked to the fact that some XCMS steps may require substancial memory while dealing with huge datasets. We also faced this problem in "old" instance and had to configure the galaxy instance to allow job re-submission with more allocated memory for XCMS modules. I guess we need to do the same with the new instance. I am not qualified to do this kind of modifications. @gildaslecorguille is this something you can handle? Based on last year frequent occurence of this issue during summer, I expect this to happen often very soon. Mélanie ---

It should be ok now. @fcastelli can you relaunch your job? xcms\_merge will now be able to use 8, or 16 and finally 32GB is needed ---
