各位老师,我定义了一个尺寸为4nm的立方体盒子,在盒子的中心放置适配体-铅离子,在CHARMM27力场下用Tip3p水解。进行到能量最小化这一步一直报错如下:
step 15: One or more water molecules can not be settled.
Check for bad contacts and/or reduce the timestep if appropriate.
Wrote pdb files with previous and current coordinates
step 21: One or more water molecules can not be settled.
Check for bad contacts and/or reduce the timestep if appropriate.
Wrote pdb files with previous and current coordinates
step 23: One or more water molecules can not be settled.
Check for bad contacts and/or reduce the timestep if appropriate.
Wrote pdb files with previous and current coordinates
......
step 492: One or more water molecules can not be settled.
Check for bad contacts and/or reduce the timestep if appropriate.
Wrote pdb files with previous and current coordinates
我只用金属离子进行分子动力学模拟,只用适配体进行分子动力学模拟,缩小盒子的尺寸等操作后依然出现同样的信息,提示One or more water molecules can not be settled. Check for bad contacts and/or reduce the timestep if appropriate. Wrote pdb files with previous and current coordinates。我检查了我的pdb文件和坐标文件没有问题,麻烦各位老师能够指明一下解决的方向。
