Performs STOCSY analysis on X by peak intensity variable defined by the chemical shift driver_peak.
Utilises the STOCSY function written by Kirill Veselkov
model = csm_stocsy( spectra, driver_peak );
model = csm_stocsy( spectra, driver_peak, 'p' , p , 'corr_metric' , corr_metric );
| Variable | Type | Default Value | Description |
|---|---|---|---|
| *spectra | csm_spectra | None | csm_spectra object containing spectral matrix. |
| *driver_peak | 1*1 | None | Chemical shift value of target intensity variable. |
| p | 1*1 | 0.1 | p-value threshold for null hypothesis of no correlation |
| corr_metric | str | 'pearson' | Correlation coefficient measure - 'pearson' or 'spearman' |
| Variable | Type | Description |
|---|---|---|
| csm_scale | csm_wrapper | Object with some stored inputs, the outputs and auditInfo. |
| csm_stocsy.output.cc | m*1 | Correlation coefficients between NMR and peakID |
