Welcome to the CSEARCH / NMRPREDICT-Server

Lehre im Wintersemester 2015

Seen in an Austrian newspaper named "Heute" (Aug 6th, 2015)

All information on CSEARCH is given here, not on Twitter, not on Facebook .....

is necessary before first usage

Why do we need such a Robot-Referee for 13C-NMR assignments
based on high-quality data and excellent algorithms ?

The publication
The referee-report
The complete story

I am quite sure you agree, that we do not want to solve future
structure elucidation problems based on such "reference material" !

New release of the CSEARCH-Robot-Referee from 2014-12-06 (Documentation)

New features:

  • Better presentation of the result of the evaluation (feedback from the Berlin 2014 presentation)

  • Summary of all evaluations performed for a particular compound can be recalled (see table at the end of each evaluation page)

  • Every evaluation has a digital signature which can be verified online – manipulation of the resulting page is therefore impossible (the chance to manipulate a page successfully is below 1 : 10**40 ! For better understanding, this corresponds to the successful isolation of one molecule out of approximately 10 PetaMoles of substance)

  • The underlying distribution of each predicted value is analyzed in detail – The result is given together with the predicted chemical shift value

  • The Robot-referee evaluates a request as 'Major Revision' or 'Reject' – A similarity search using 67,000,000 predicted CNMR-spectra based on the PUBCHEM-Compounds is automatically launched

New release of the CSEARCH-Robot-Referee from 2015-09-04 (Documentation)

New features:

  • Create a private database – Every user can select previously performed evaluations as reference database for upcoming requests. It is strongly recommended to use only datasets of superior quality for this purpose. This user-database is fully searchable and contributes to every prediction/evaluation as CSEARCH-databases do.

  • Donate spectra to the public – There is a possibility to donate assignments after a predefined period of time for further use within CSEARCH-databases

  • Online help – When hovering with the mouse-cursor over certain text-portions a descriptive help-text pops up

A few 'Highlights' of assignment errors as found in the literature

Assignment errors

Spectral similarity-search based on 16,4 millions predicted CNMR-spectra calculated for the PUBCHEM-structures including ranking of resulting hitlist

Spectral similarity search with ranking

16,4 millions of predicted CNMR-spectra

Spectral similarity-search based on 71 millions predicted CNMR-spectra calculated for the PUBCHEM-structures without ranking of the resulting hitlist

Spectral similarity search without ranking

71 millions of predicted CNMR-spectra / Pattern search

Spectral similarity-search based on 61 millions predicted CNMR-spectra calculated for the PUBCHEM-structures with ranking, separate deviation for every shiftvalue and unknown multiplicities possible
