Dear all, I have a Se-Met SAD data which diffracted to 2.8A (peak wavelength). The space group is P1. The map from SAD autosol and autobuild still gives crappy map, I can only see one continous alpha-helix density with all other density fragmented and difficult to identify. I suppose it is because of high mosaicity (1.5), low data redundency, and some radiation damage. Now I want to use mocular replace (sequence identify ~0.26) plus SAD data to give better map. 1. The result from MR is shown below and the density is poor as the sole SAD map: REMARK Log-Likelihood Gain: 121.374 REMARK RFZ=3.4 TFZ=100.0 PAK=0 LLG=29 RFZ=3.7 TFZ=5.4 PAK=0 LLG=69 RFZ=6.1 TFZ=4.0 PAK=0 LLG=97 RFZ=5.6 TFZ=5.0 PAK=0 LLG=118 LLG=121 2. I then tried to combine MR model and SAD data set phenix.autosol seq_file=zntb-sd.seq sites=14 atom_type=Se data=output-peak.sca sg="P1" cell="44.355 56.687 58.451 61.061 82.013 82.740" resolution=3.0 input_partpdb_file=AutoMR_run_1_/MR.1.pdb The program failed to run with such error message: Failed to carry out AutoSol_score_ha_solutions: [Errno 2] No such file or directory: 'AutoSol_run_3_/TEMP0/phaser_mtz.hand.mtz' I do not know where to get this phaser.mtz.hand.mtz file or how to generate it. Does anyone know? -- Qun Wan Department of Pharmacology, Case Western Reserve University 10900 Euclid Avenue, Cleveland, OH 44106 email: [email protected] lab phone: 216-368-3337
Hi Qun, I'm sorry for the problem! That error message means that autosol made a mistake, not that you are missing something. I am hoping that perhaps you are not using a very recent version phenix. Can you possibly try updating with a recent "nightly build" from the phenix web site and see if that fixes this problem? If it does not, please let me know and I will fix it. All the best, Tom T
