本帖最后由 虔诚的人 于 2018-5-10 21:25 编辑 sob老师,您好 我在martini跑蛋白和极化水体系中,跑nvt遇到这样的问题,请问这么解决: [td]WARNING 1 [file CG.top, line 18]: | The bond in molecule-type Protein_A between atoms 1 BB and 3 BB has an | estimated oscillational period of 9.7e-02 ps, which is less than 5 times | the time step of 2.0e-02 ps. | Maybe you forgot to change the constraints mdp option.[/td] 我的mdp文件,其他都是正常的设置。 ; Bond parameters constraints = none ; No constraints except for those defined explicitly in the topology constraint_algorithm = Lincs ; LINear Constraint Solver continuation = no ; lincs_order = 4 ; also related to accuracy lincs_iter = 1 ; accuracy of LINCS lincs_warnangle = 90 ; maximum angle that a bond can rotate before LINCS will complain 这虽然是个警告,-maxwarning 1可以是模拟进行,但是后面就会报原子超出约束90 我想了一些方法解决这个问题,但是还是报错 [td]Step 435516, time 2177.58 (ps) LINCS WARNING | relative constraint deviation after LINCS: | rms 0.110531, max 11.324476 (between atoms 89 and 90) | bonds that rotated more than 90 degrees: | atom 1 atom 2 angle previous, current, constraint length | Wrote pdb files with previous and current coordinates[/td]恳请sob老师指教! |

第一次发帖,请见谅,复制粘贴的着急就没改。我改了之后又同样的发了一次,您可以查阅,如果方便我可以加您 ...
