C-CODE
This field contains the recognition program by the sequence-dependent conformational or physico-chemical feature or Mean recognition in the ‘C’ language of the ANSI standard.Each C program documented within the B-DNA-Video entry has a check-box in the MENU window of the Recognition Tools (see field
