MetaProSIP: automated inference of elemental fluxes in microbial communities

 Info
MetaProSIP has been fully integrated into OpenMS. No additional installer is required anymore.

Update: MetaProSIP now supports labeling experiments with heavy water (D, 18O)

Download an updated KNIME workflow: here

Advanced workflow including mass recalibration, alignment, and ID pooling: here

Requirements

  • High-Resolution MS, CID, or HCD MS2
  • Developed and tested on orbitrap instruments
  • MS1 and MS2 need to be centroided (either on acquisition, conversion or in a workflow using the TOPP tool HiResPeakPicker)

For additional information on sample handling and acquisition please refer to the original MetaProSIP publication.

FAQ:

  • Q: I get an “Error: Process returned with a non-zero status.“ “Error: File not found (the file ‘C:/Users/USER/AppData/Local/Temp/cluster_result_15NMix_1_3_a_picked_yD9N.dat’ could not be found)“.
  • A: Make sure that a suitable R version (32 bit) and the R packages are installed and add the directory to your PATH environment variable.
  • Q: What do the columns in the group output refer to
