#include <tagUtils.h> void shift_contig_tags( GapIO *io, int contig, int posn, int dist);
This function moves tags within a contig with number contig. All tags starting at position posn, or to the right of posn are moved to the right by dist bases. dist should not be a negative value.
The function is used internally by (for example) algorithms to add pads to the consensus or for joing contigs.
