Validation of Consensus Run
Verification of Consensus Assignments
1. Create a working subdirectory, for example, cyana21/calc2.
2. Copy consensus peaklists (n_cons.peaks, ali_cons.peaks and aro_cons.peaks) into this subdirectory.
- If using CARA, re-integrate the peakslist and export them.
3. Copy init.cya, XXXX.seq, XXXX.prot and stereofound.cya from the CYANA automated run (cyana21/calc2). Rename stereofound.cya into stereo.cya
4. Copy GridSearch.cya, CALC.cya and talos.aco from the found subdirectory. Modify GridSearch.cya to read cons.upl instead of short.upl.
5. Create UPL file cons.upl using run_caliba.cya (see below).
6. In CYANA 2.1 run GridSearch.cya
7. In CYANA 2.1 run CALC.cya for manual structure calculation with only consensus constraints.
8. Clean violations the same was is in Verifying Local NOE Network with FOUND (HABAS) and try to keep TF < 1.0.
- For the violated NOE, re-integrate the peaks first if it is overintegrated (in XEASY).
- Unassign peaks, which appear at spectral artifacts.
- If violation persisit while peak integrals are correct, then modify the calibration parameters.
9. Verify the additional stereospecific assignments made in this run. Swap the atom groups if needed.
You may want to run an additional iteration of consensus assignment, though it is usually not necessary:
===
Acceptance Criteria
A successful consensus run shall satisfy:
- Both program CYANA and AutoStructure automatic structure calculation deliver converged structure.
- The structures from program CYANA and AutoStructure are similar, the RMSD value between the mean structures from both programs should be less than the sum of pairwise RMSD values of the two structure families.
- The manual run of CYANA structure calculation with distance constraints from consensus assigned NOEs delivers converged structure, the pairwise RMSD of the structure family shall be less than 3A.
- The yield of consensus assigned NOEs shall be large than 50%.
