The simulation data of two (imperfect) palindromic motifs

There are two subdirectories, each containing simulated data 
for one palindromic motif. The dataset of each motif consists
of the following two files:
 1) simu.mf -- training true sites
 2) simu.Test.fa -- testing sites

Simulation Parameters
 1) Base Frequencies
  We use a uniform distribution in this simulation, 
   That is, the frequency of each base at each position is 0.25.
   False and true sites are simulated under the same uniform 
   distribution, but true sites are palindromic
   sites generated with the following probabilites: 
 
 2) The probability of forming a complementary base pair (A-T or G-C) 
    between two corresponding positions of two palindromic motifs
    are given in the following table:

		Position	|	pairing probability
	Pos-1	|	Pos-2	| motif_A	|	motif_B
	----------------------------------------------------
	0	|	11	|	0.99	|	0.90
	1	|	10	|	0.95	|	0.85
	2	|	9	|	0.90	|	0.75
	3	|	8	|	0.65	|	0.65
	4	|	7	|	0.50	|	0.50
	5	|	6	|	0.25	|	0.25
