Hello R I have some data from a number of gels showing the distance of bands in each gel and lane. My problem is to align these values by some method. It has been suggested to me (by a Matlab expert) that I could use Spectral methods such as COW (correlation-optimised warping) or PAGA (peak alignment using GA). I have searched but cannot find if there are equivalent packages that do this in R. Any suggestions from anybody on where to look? The idea is, I think, to create a matrix of all the possible values, mark them as present or not, and then perform an alignment. i.e a matrix something like: lane1 lane2 lane3 ... .001 1 0 0 etc .002 0 0 0 etc .003 ... Is there a more direct method than using spectral methods? Has anybody done something equivalent? Thank you in advance for any help. Regards John Seers
