Hello, Please I want to call the peaks from bigwig file, so I converted it to bedgraph formate, and run MACS, it worked really fine and I got the output, however suddenly it turned red and gave me this message: The job creating this dataset has been resubmitted ```auto NFO @ Sun, 02 Jun 2019 12:45:55: # Command line: callpeak -t /data/dnb02/galaxy_db/files/009/613/dataset_9613622.dat --name bigWigToBedGraph_on_data_13 --format BAM --gsize 2700000000 --keep-dup 1 --qvalue 0.05 --mfold 5 50 --bw 300 # ARGUMENTS LIST: ``` I have no idea what happened! and how to fix it! Could you please help me! Thank you in advance! Sham ---

Hi @shamjdeed What public server are you working at? Appears to be Galaxy EU [https://usegalaxy.eu](https://usegalaxy.eu). But please confirm. If working somewhere else, please note the URL (if public) or describe more about your local/cloud Galaxy (what Galaxy version, where/how you sourced and installed it, last time it was updated). There are some known issues with metadata assignments with a fix in progress but not finalized yet/deployed to all public servers yet. Meanwhile, allow the job to rerun. If it fails, try running it again. As far as I know, only some clusters are presenting with this problem as a server-side issue (or at least at Galaxy Main [https://usegalaxy.org](https://usegalaxy.org) – which doesn’t automatically rerun failed jobs, so you are not working there). The problem could also be due to inputs, parameters, or other issues. Once we know where you are working, we can follow-up based on that information. Thanks! cc @bjoern.gruening @hexylena @nate ---

Hello @ jennaj, Thank you for your reply Yes I am using Galaxy EU, and I am in Hungary! (Galaxy Version 2.1.1.20160309.6), I did not install it I use it on line after signing in in my account! I run it again and it did not work! Thank you! ---

Hi @shamjdeed Whenever you have errors like these, we recommend submitting a bug report. That’s often a fast way to get help. Looking at the `(i)` information icon, and checking the `stderr` and `stdout`, I see the following. ```auto INFO @ Sun, 02 Jun 2019 12:45:55: # Command line: callpeak -t /data/dnb02/galaxy_db/files/009/613/dataset_9613622.dat --name bigWigToBedGraph_on_data_13 --format BAM --gsize 2700000000 --keep-dup 1 --qvalue 0.05 --mfold 5 50 --bw 300 # ARGUMENTS LIST: # name = bigWigToBedGraph_on_data_13 # format = BAM # ChIP-seq file = ['/data/dnb02/galaxy_db/files/009/613/dataset_9613622.dat'] # control file = None # effective genome size = 2.70e+09 # band width = 300 # model fold = [5, 50] # qvalue cutoff = 5.00e-02 # Larger dataset will be scaled towards smaller dataset. # Range for calculating regional lambda is: 10000 bps # Broad region calling is off # Paired-End mode is off INFO @ Sun, 02 Jun 2019 12:45:55: #1 read tag files...
