Title: METLIN information extraction
Post by: Ricca on September 22, 2011, 10:09:25 AM
Hi, is there a way to manually generate the link to Metlin database without using diffreport method?? I see in the manual that is possible when you have an MS^n experiment while I have only a MS experiment with no fragmentation.

Best

Hi Ricca,

You can use METLIN Batch Search (http://metlin.scripps.edu/metabo_batch.php (http://metlin.scripps.edu/metabo_batch.php)) to find the metabolites that you are interested with.  You can simply enters masses (up to 500 unique masses), select adducts as targets, and set tolerance (either ppm or Da).  Please let me know if you have further questions using METLIN DB.

Cheers
