Re: [ccp4bb] Looking for help to read 4mm data tape

2020-10-16 Thread Jon Cooper
Hello, one of my favourite subjects. 4mm is DAT tape, I believe. You need to find out if they are VAX or unix tapes. There is a VAX DAT tape drive which I gave to Jeremy Cockcroft at UCL Chemistry last year - it definitely worked about 12 months ago and allowed an early 90's tape to be read.

[ccp4bb] Looking for help to read 4mm data tape

2020-10-16 Thread Xiong, Jian-Ping
Sorry for an unrelated request. One of my colleagues is trying to fill in the Table 1 from datasets collected ~20 years ago. Unfortunately, the log files were saved on 4mm data tapes (2gb/4gb, I believe). We just couldn't find such old computer to read these tapes in our local areas, so would

Hi Christian, Thanks for pointing out that option. I will definitely try it out. Perhaps my tutorial can be adapted to this way of making the models. /Derek On 16 Oct 2020, at 10:26, Christian Roth mailto:christianroth...@gmail.com>> wrote: HI Derek, I don't know which options you need, but

Hello, When I further refine my structure the N+1 is gone and it becomes a normal N again. So it is very much possible this is related to geometry. Thanks everyone (Esp. to Jon) for the input! Sam On Fri, 16 Oct 2020 at 19:31, Jon Cooper wrote: > Hello Sam > > thanks for the pictures. It

Hello Sam thanks for the pictures. It looks like the guanidinium group of the first Arg is not very planar. I don't know the detailed nuts-and-bolts of how Coot and Refmac handle this but the problem may arise from the initial geometry at the affected nitrogen being off-target. Best wishes,

HI Derek, I don't know which options you need, but there is the interactive task of model preparation with mrbump and ccp4mg in the bioinformatic tasks, which might allow what you want to do. Cheers Christian On Thu, Oct 15, 2020 at 11:02 PM Derek Logan wrote: > Hi all, > > I'm looking for

Dear all I attach herewith the Arg concerned. I actually saw no issue in Coot when I checked residue info. The issue was repeatable using both Refmac from Coot and from CCP4i. I rectified the issue simply by changing "N+1" back to "N" using a word editor, but would surely be glad to know more
