We are trying to get SAD phases using a Ta6Br12 cluster using phaser. Sites were found with ShelxD and we have set the ha.pdb in the form:
ATOM 1 TX HAT 1 24.569 195.940 54.912 1.00 20.00 TX and we define the scatterer in phaser.inp with: SCATTERING TYPE TX FP = -25.31 FDP = 11.7 FIX OFF but get the error: INPUT ERROR: Type T not element or cluster We've tried a few permutations of columns 14-15 and 78-79 of ha.pdb but phaser hasn't been able to successfully interpret the scattering type. I haven't been able to find detailed information about the format of the input pdb file with the HA sites to bypass this error. We're using phaser from ccp4-6.3.0 distributed by sbgrid. Any help will be much appreciated, Kevin Jude
