Usage: gkmmatrix [options] <pos_seqfile> <neg_seqfile> <output_kernel>

 build kernel matrix of gkm-SVM

Arguments:
 pos_seqfile: positive sequence file (fasta format)
 neg_seqfile: negative sequence file (fasta format)
 output_kernel: output kernel file

Options:
 -t <0 ~ 5>   set type of kernel function (default: 2)
                0 -- gapped-kmer (gkm)
                1 -- estimated l-mer with full filter
                2 -- estimated l-mer with truncated filter
                3 -- truncated filter + radial basis function (RBF)
                4 -- truncated filter + positional weights (PW)
                5 -- truncated filter + PW + RBF
 -l <int>     set word length, 3<=l<=12 (default: 10)
 -k <int>     set number of informative column, k<=l (default: 6)
 -d <int>     set maximum number of mismatches to consider, d<=4 (default: 3)
 -g <float>   set gamma for RBF kernel (-t 3 or 5) (default: 1.0)
 -v <0 ~ 4>   set the level of verbosity (default: 2)
                0 -- error msgs only (ERROR)
                1 -- warning msgs (WARN)
                2 -- progress msgs at coarse-grained level (INFO)
                3 -- progress msgs at fine-grained level (DEBUG)
                4 -- progress msgs at finer-grained level (TRACE)
-T <1|4|16>   set the number of threads for parallel calculation, 1, 4, or 16
              (default: 1)
