Method and apparatus to facilitate automated transcription of NMR spectra into a textual report using a graphics tablet

摘要

A computer assisted method and apparatus for transcribing nuclear magnetic resonance (NMR) spectrum into a textual report. A graphics tablet containing a pointing device is used. A stacked plot containing a NMR spectrum is placed on the tablet and is calibrated. The user selects the location of the peaks within the signals in the spectrum using a pointing device. Selected peaks are communicated to application software executing on a computer coupled to the graphics tablet. The application software converts the coordinate data of the user-selected peaks into spectral positions that are used to generate the textual report. The user also controls the selection of the signal type as well as the number of protons contained in the signal. The application software determines the exact coordinates of the signal, but does not control selection, location or characterization data of the signal. This eliminates errors caused by totally computer-controlled text reporting systems.
