Who else here is using the PiMP platform (designed by Glasgow Polyomics, UK) to analyze their metabolomics data? I used this platform and extracted the data in a .csv format. Then I loaded them on metaboanalyst.ca, but the metabolites names and pathways that were apparent on PiMP, disappeared, showing only ms1_peak_id on all graphs and tables.
How to export the results .csv field with metabolite names rather than ms peak id? Also i tried copying the peak's id to identify it on KEGG or HMBD, without success of identification. I am newly involved in such analyses, so any help or advices to handle this is welcome.
How do I identify peaks from biological compounds? Thank you All
I didn't work on PiMP platform, but I do worked on Metaboanalyst. I most important think in metaboanalyst is the data entry as csv file. First check your saved csv file. It should have sample name in columns and metabolites in rows. The MS id and other details are not required when you work in metaboanalyst.
So, my recommendation is create a new csv file with sample name, metabolites and their concentrations only.
Thank you and all the best. If you have any further query you can always mail me...
effectively my .csv file does not have metabolite names but instead ms1 peak identity. so I am looking for a way to relate this id to metabolites names.
In that case, first you can identify the metabolite name of ms1 peak using NIST library or XCMS software wherein you have to upload raw data, and proceed further.
