If you want to look for structures in one sequence, then use the program copy to make a copy of xbook in ybook. hlist: the helix listing for xbook and ybook made by program helix mlist: the matrices listed out. Sequences from the x book are printed vertically, while those from the y book are horizontal. helices are printed as a set of numbers: 1 means gt base pair 2 means at base pair 3 means gc base pair if mlist is wider than your printer, use the split program. matrixp: parameters to control the mlist If matrixp is empty, default values are used. otherwise, the first line contains one number. If this number is a positive integer, it specifies the minimum length helix in base pairs from hlist to record in mlist; if this number is a negative real number, it specifies the maximum energy in kcal of the helixes written in mlist. output: messages to the user description Matrix produces a dot matrix for the two books. Only helices of some length (or longer) or of some maximum energy (or less) are printed. The helices are made using program helix. documentation delman.use.comparison J. V. Maizel, Jr. and R. P.
