When started with no options, a summary of commands is given. With two protein structures presented as
arguments, the TM-score uses the length of the second protein to be normalised. The final structural
alignment is invariant to any of the options below.
-Lnumber normalises TM-score by an assigned length (in aa)
-a normalises TM-score by the average length of the two structures
-b normalises TM-score by the length of the shorter of the two structures
-c normalises TM-score by the length of the longer of the two structures
-ofilename Run TM-align and output the superposition to 'filename.sup' and 'filename.sup_all'. The
output files serve as scripts to the program rasmol. To view the superimposed structures of the
aligned regions call
'rasmol -script TM.sup' To view the superimposed structures of all regions
'rasmol -script TM.sup_all'.
