I have a FASTA file contains unique k-mers with the read length is the k-mer size:
Then I used the API of gatb-core-1.0.6-Linux :
Graph::create ((char const *)"-in %s -kmer-size %d -abundance-min 1 -nb-cores %d -out %s", xxxx);
There should be 11,571,887 unique k-mer in my file, but the graph build by this file contains only 11,065,132 unique k-mers.
I think this program lost some useful k-mers while storing k-mers.
