Dear Shiva, I was wondering if there is any IOS5 based app to display protein models, which are not in public database, on Iphone. Just yesterday, Dr. Ishitani at Tokyo university released Cuemol for iOS. http://itunes.apple.com/us/app/cuemol/id496236710?ls=1mt=8 Although not free, iMolview

Dear Debajyoti, The way I check the chirality is to compare the fitted compound with the structural formula. In coot, I rotate the ligand such that it has the same orientation as in the formula and check that the out of plane group goes in the right direction. However, it happens quite often

Dear Shiva There is an app called Molecules for displaying models but that utilizes coordinates from RCSB and pubchem. You can also import your structure directly from itunes in pdb format iMolview is not free but is very nice (better than Molecules :-) cheers Simone On Jan 27, 2012, at

As someone stuck maintaining an SGI for a user who resolutely refuses to abandon Showcase or Ribbons for IRIX, I sympathize with those cases where one simply has to get an old computer system to work. Anyway, we don't have the relevant library file in our freeware directories either. However,

Dear Crystallographers, I cannot think why any of the various flavors of Rmerge/meas/pim should be used as a data cutoff and not simply I/sigma--can somebody make a good argument or point me to a good reference? My thinking is that signal:noise of 2 is definitely still signal, no matter what the

Hello All, Do any of you RNA structural biologists know what is the 3 letter code for 1'-deoxyribofurnaose-5'-phosphate (abasic site in RNA)? I found that the 1'2'-dideoxy is 3DR, but could not find a lead on the 1'-deoxy. I scoured HIC-UP to no avail, which I think is the most comprehensive
