Briefly, in the COLMARm method, user can submit experimental C-1 H HSQC, 1 H-1 H TOCSY and 13 C-1 H-1 H HSQC-TOCSY data to perform high confidence searches and identification. First, a computational matching of the experimental HSQC data to database spectra leads to a visualization of matched peaks and a list of candidates is presented. Secondly, the user will be able to validate the identification made with the HSQC using the (HSQC-)TOCSY data that lead to a greater selectivity due to the exploitation of the information transferred via chemical bond within the 1 H/ C-1 H spin system, in a scalar coupling ( 2,3 JHH). Spectra can be processed using different software and exported into a file that will be readable by COLMAR (e.g. MNOVA's csv files and NMRPipe's ft files). The importance of COLMAR to the scientific community is reflected in more than 70 citations and more than 2000 registered views.
