Minor and major groove widths: direct P-P distances, and 'Refined' P-P
distances which take into account the directions of sugar-phosphate
backbones. Subtract 5.8 Angstrom from the values to account for the
vdw radii of the phosphate groups, and for comparison with Curves+.

I downloaded and checked the latest DSSR for --circular-analyze and the groove information looks great.Glad to hear!
There is an issue with the parameter data section (both wimple and based on consecutive C1'-C1' vectors): If I have N base pairs I will have N base-pair steps for circular DNA. The output stops at the N-th base pair but there is still one step of information between the Nth-1st base pair.That needs to be changed since currently the circular feature is only applied to groove widths. Do you have any formatting suggestion?
Finally, at the bottom of the output file is this truncated Global Linear Helical Axis section. Was that by design as you were testing the new code or is this a bug?That's 'by design' for now. What changes do you like to have, if any?
N-1 C-G 14.41 14.37 19.81 19.75 N G-C 14.32 14.27 19.86 19.79 1 A-T 14.32 14.27 19.86 19.79 |
Well, when I get my circular reference frame files, my last frame is numbered 1 instead of N+1. My last row in my circular parameter file is the first base-pair.Fair point. I'll see how I can accommodate it in DSSR in the near future.
So, if anything, I would suggest the following:
N-1 C-G 14.41 14.37 19.81 19.75
N G-C 14.32 14.27 19.86 19.79
1 A-T 14.32 14.27 19.86 19.79
It's been my experience that there doesn't need to be a new way of arranging the base pair nor the base pair step parameters except that the first base pair will need to be repeated at the end (N base pairs so N base pair steps) in order to collect the last base pair step data.
