unknown step values

[yangxi]

Hi,all

  I'm currently dealing with nucleosome structures.My problem is some dimer steps in the.out file have no values

E.G. dimer steps like "21 CC/GG"  

    step            Shift     Slide      Rise       Tilt        Roll     Twist

  20 TC/GA     -0.04      0.59      2.61      7.59     12.27     18.30
  21 CC/GG      ----         ----      ----        ----       ----       ----
  22 CC/GG      1.22      0.53      1.78     24.42     3.72     32.21

I want to know the reason, and how can I handle step values like this?

Things would have been much clearer if you have provided a reproducible example, as requested.

Lacking that info, I would guess there are some missing bps as identified directly by 'find_pair'.

You might also try '-c' option with 'analyze'.

Hi, Xiang-jun

I do as you suggest,trying '-c' option with 'analyze', and it really works. Now all the dimer steps have values.I also compare current values with previous ones and find that they remain the same (except the previously unknown ones, of course)  
Thanks a lot for your reply!
