NOTIFICATION: Permanent migration of all CSB.DB services and functionalities on 1.1.2016.
Herewith we inform you that all CSB.DB databases have been migrated at the beginning of 2016. This includes all gene correlation and expression databases, the GMD@CSB.DB module and all associated databases
The BestFit software, a tool for non-aqueous fractionation data analysis, will also be available by the Experimental Systems Biology Research Group headed by Dr. Patrick Giavalisco.
We thank all users, contributors, and collaborators of CSB.DB at the Max Planck Institute for their long-standing support.
Yours sincerely, the CSB.DB Curator and the CSB.DB Developmental Core Team

Mass Spectra Query: MSRI: Mass Spectrum Information Page back to top

Basic: The mass spectrum information page provides access to the underlying evidences and in-depth information for compound identification. The obtained results are organized as follows:

Mass Spectrum Information

Mass Spectrum Information for Entry: 141006_101_4
entry-id GMD entry-id for the obtained spectrum (mpimpid_itrid_number)
date date of last modified
mpimp-id MPIMP-ID for the substance from which spectrum obtained. If you click on the link you get all access to all entries for this substance.
itr-id isotope characteristics for the spectrum
ri observed rtetion time index
mass [quantification] Quantifier: mass trace normally used to quantify
Qualifier: mass traces normally used to qualify the identification
mpimp-id [role] A raw category for the substance
experiment experiment id
method Method used to generate / obtain this spectrum. If you click on the link you get access to in-depth information for the method used.
library Contains the (pre-computed) library name in which the mass spectrum is harboured. If you click on the link you get access to details of the library ass well as a direct link to download the library.
name The substance name (if mass spectrum identified) of the substance to generate the mass spectrum. If you click on this link a new search with this name will be invoked.
match If the mass spectrum assigned by match here you can find the details. A matched mass spectrum is represented square brackets with first the match values followed by the substance name / synonym. If you click on this link a new search with this name will be invoked.
assignment The mass spectrum was assigned by: identification (added substance) or match procedure.
isotop type isotop type
sample description a short sample description
compound name the compound name for the substance
compound class the compound class for the substance
sample contribution the sample was provided by
mass spectral contribution the mass spectra was provided by
citation citation information
mass spectrum [fragment number] number of fragments for this spectrum
mass spectrum [fragments - relative intensity] mass spectrum
platform platform used to obtain the spectrum
mass spectrum search run mass spectrum search with the given spectrum, the observed RI for the respective technology platform
graphical visualization of the spectrum
