Hello all, I am trying to do non-linear retention time alignment of LC-MS spectra using the bioinformatics toolbox and I'm having a very difficult time..
It seems like the function I need to use is samplealign, but it required a matrix of data, when I have a cell array of peak lists. If I convert the cell array of peak lists to a matrix (using msppresample for instance), I lose resolution, unless set N to something ridiculous, in which case the matrix is mostly zeros and samplealign errors. I'm not sure what to do...
