This is an addition to my strategy Green and blue nucleotides on a strand, where I take in to account, that a strengthening appears to be taking place right after the middle of the design. (For the theory behind this see my getsat post Slightly skewed energy tendency for the whole lab)
So this strategy should be excactly as my Green and blue nucleotides on a strand, with the only exception, that I allow a blue/green line on a strand that is one nucleotide longer than stated in my strategy - if this longer blue/green line is found up to 11 nucleotides after the exact middle of the design (this 11 nt limit may have to be higher, if we are starting to making bigger lab puzzles)
So here my strategy is again with the addition.
I would like to ad a strategy about how many blue and green nucleotides I will allow in line right after each other on a strand of a certain length.
In a string 3 nt long, allow max 3 blue/green nt in line on a strand
In a string 4 nt long, allow max 3 blue/green nt in line on a strand
In a string 5 nt long, max 3
In a string 6 nt long, max 4
In a string 7 nt long, max 4
In a string 8 nt long, max 4
In a string 9 nt long, max 4
In neckarea up to 6 is allowed. (including this number)
Penalize with -1 for each extra blue/green nucleotide above the number allowed,
Except if one extra nucleotide is found in the area (number of nucleotides divided with 2 and found between this area and + 11 nucleotides)
