dnax_unpack_4bits(3) - encode DNA using four bits per nucleotide
LIBDNA, 2019-09-19
#include <kloetzl/dna.h>
char *dnax_unpack_4bits( const unsigned char *begin, const unsigned char *end, char *dest);
Description
The dnax_unpack_4bits() function decodes the nucleotides previously packed with dnax_unpack_4bits(3). The decoding of characters is compatible to the Nucleotide Archival Format.
This function always writes an even number of bytes.
Return Value
The return value points one byte past the last character written.
Example
const char str[] = "ACGT-W";
unsigned char packed[3] = {0};
char buffer[7] = {0};
dnax_pack_4bits(str, str + 6, packed);
dnax_unpack_4bits(packed, packed + 3, buffer);
assert(strcmp(str, buffer) == 0);
