Selecting this option causes the colour scheme to be applied to - only those residues that occur in that column more than a certain + only those residues that occur in that column at least a certain percentage of the time. For instance, selecting the threshold to be - 100 will only colour those columns with 100% identity.
-To be coloured, a residue must match the consensus (most commonly occurring) residue for the column (or joint equal consensus).
+ 100 will only colour those columns with 100% identity, and selecting 50 will shade residues appearing in least 50% of the rows (or sequences) in each column.The percentage calculation may include or exclude gaps in the column, depending on the option selected for the consensus calculation.
-With a threshold of 0, colouring is unchanged (including non-consensus residues).
+With a threshold of 0, colouring is unchanged.
