Dear Omics Forum
I would like to share my result regarding METLIN ID conversion to KEGG ID conversion of metabolites. I am using the Metabolite ID Conversion (https://new.metaboanalyst.ca/MetaboAnalyst/upload/ConvertView.xhtml) with the METLIN input.
First of all, if I add the adjointed *.txt with the METLIN IDs I would like to convert, it is not recognized at all.
METLIN_ID_LA10_A12_Positive.txt (844 Bytes)
Secondly, if I add the values inside the *.txt into the text box for compound ids, the results are very lacking. I believe it is due to the databases used, but i don’t really know.
name_map.csv (5.2 KB)
As you can see, from all the input data, not only there have been some data losses (where have ten compounds go?) but also only 2 have been identified, as I would like, from these METLIN IDs, obtain either their KEGG IDs or their HMDB IDs.
The main goal of compound mapping is for functional analysis. Therefore, the support for METLIN ID is limited to those with HMDB/KEGG compounds. You will get more METLIN IDs match from HMDB IDs, not vice versa.
Thank you for your answer!
