Hi Ron Mmmm... not really but thanks for the info:) I have my Bfactor column assigned in percent conservation so the B value ranges from say 30% to 100%. I want to colour my molecule accordingly. Pymol allows B factor colouring but seems only to allow 3 colour choices. It used to allow 4 colou

Hi, I'm aware of two ways to do this: by writing the colour as a word, e.g: color white, (mypdbfile//A/*/*) which will colour a whole chain. Or by using rgb colours, e.g: set_color newcolor0 = [1,1,1]; color newcolor0, (mypdbfile//A/2/*) which will colour individual residues (residue 2 in this

Dear Everyone Slightly off topic... I am trying to colour a structure by B factor in Pymol. More specifically I am colouring conserved residues (value in b factor). I want to use 4 colours - say white, yellow, orange, red. However it seems that Pymol now only allows 3 colours to be used - I t
