Fold cutoff by TM-score:
By default, the Fold cutoff is set as TM-score>0.7.
This value can be changed for modifying the structure
sequence variations.
TM-score should be in [0,1], with a higher value indicating a closer structural
simularity. A TM-score >0.5 indicates that proteins have similar fold.
If a value outside [0,1] is input, a default value of 0.7 is used.
