[ccp4bb] on building a helix fragment by coot

Dear All, Caused by poor resolution, I can only build a series of Ala into my helix density (for sure the density is for helix). Then I tried to use the dock sequence in the extension of the Coot to change to my target sequence. Coot says it was not confidence on the alignment, thus it did not

Interestingly, we have both systems working in our lab. Our old station is 7 years old with FX3700, view sonic monitor and 3-pin stereo emitter. My new one has K5000 and VG278HR, which just requires a pair of nVidia shatter glasses. Hope this helps. Aidong On Apr 2, 2015, at 7:20 AM, Andreas

Alright, thanks! It's a good thing, then, I spent the afternoon brushing up on matrices. I guess the next, probably more general question for the bb is: which utilities export an NCS transformation matrix with more precision? *superpose* and *gesamt* only export three decimals, though I'm sure the

Re: [ccp4bb] Strange Ancient Diffraction Pattern...

These diffraction patterns, called "matzo" (Hebrew: מַצָּה‎) have been observed already by the ancient jews, and it is thought that the invention of the millstone (see http://galleryhip.com/millstone.html) is a consequence of early detector technology to produce these images. Andrea. On 01/04

Re: [ccp4bb] Sortwater NCS Matrix input

I think you are on the right track - There are not enough decimal points in your matrix elements to pass the orthonormal test. This test checks that the length of each row (x^2+y^2+z^2) is equal to one and the dot product of each row with every other row is equal to zero. If the values on your

Hi ccp4bb, I'm trying to solve a problem I never quite figured out in the past. I'd like to use the *sortwater* utility to send my picked waters to various protein chains, and to give them the same residue number if they are NCS-equivalent, as the manual outlines. http://www.ccp4.ac.uk/html/sortw
