COLMARvista: an open source 2D and pseudo-3D NMR spectral processing, visualization, and analysis software in JavaScript

COLMARvista is presented as a new, highly versatile software for the easy and intuitive processing and visual inspection of 2D and pseudo-3D NMR data both for uniformly and non-uniformly sampled datasets. COLMARvista allows fully autonomous processing of spectra, including zero-filling, apodization, water suppression, Fourier transformation, and phase correction. Its full integration with DEEP Picker and Voigt Fitter programs allows the automated deconvolution and reconstruction of the experimental spectra for highly quantitative analysis, from compound concentration determination to the extraction of cross-peak specific relaxation parameters, even for signals affected by significant overlap with other peaks. COLMARvista is based on JavaScript and, hence, it is computer-architecture and operating-system independent including its advanced graphics. It runs on all recent web browsers and does not require a potentially elaborate operating-system dependent installation. COLMARvista may serve as a paradigm also for other software projects to prevent the stockpiling of once powerful legacy software that became frozen in time, thereby ensuring continuing progress of the NMR field and its software for future generations of NMR spectroscopists.
