%% TODO - reinstate this exercise about reinstating presets
-%
+% * gapdist can't be set to non-integer values. 1 seems to give a good RMS
+% * looks like the jabaws service definition for clustalw has a copy-paste error in the description of transition weighting
+% * need to fix superposition instructions
+% * not really clear which is better without seeing number of superimposed positons. can that be viewed ?
