correction of retention times in liquid and gaz chromatography
x2_new_rt=obiwarp(x1_master,x2_slave,score,local,nostdnrm,factors,gaps,init_penalty,response)
a Div structure or a matrix of dimensions (n1 x q)
a Div structure or a matrix of dimensions (n2 x q)
the score function; 4 possibilities:
'cor': Pearson correlation coefficient (by default)
'cov' : covariance
'prd' : dot product
'euc' : Euclidian distance
local alignement rather than global (by default)
no standard normalization; by default the score matrix values are mean centered and divided by the standard deviation (unless all values are equal)
local weighting applied to diagonal/gap moves in alignment; two numbers between entre brackets separated by a comma
ex: [2,1] gives an unbiased alignment
gap penalties, initiate then extend; two numbers between brackets separated by a comma
the default values are:
'cor'-> [0.3, 2.4]
'cov' -> [0,11.7]
'prd' -> [0,7.8]
'euc' -> [0.9,1.8]
penalty for initiating alignment (for local alignment only)
by default: 0
responsiveness of warping; 0 will give a linear warp based on start and end points; 100 will use all bijective anchors
a vector of dimensions (n2 x 1)
