Simulation of cDNA-AFLP with sequential digestion protocol on Arabidopsis RefSeq data was performed using marking enzymes MboI and FatI and six releasing enzymes with different frequencies of occurrence: frequently cutting enzyms H (TasI and MseI), enzymes with a medium frequency of occurrence M (BsaWI and TatI) and infrequently cutting enzymes L (AcyI and CfrI). For each permutation of H, L and M enzyme classes, cDNA-AFLP were simulated for 8 permutations of the releasing enzymes (RE). Average values of coverage, redundancy, PCR effort and fragment length for each permutation of H, L and M were calculated.
