我之前用crest2.1.2能正常使用,更新到3.0.2之后做构象搜索时光速提示MTD不收敛然后停止运行,此外做过渡态构象搜索,用constrain的MTD时提示初始结构优化失败,请问版本更新是更换了命令关键词吗?
以下是做中间体构象搜索关键词:crest mtdP1-2.xyz --shake 0 --noreftopo --cluster --chrg 0 --uhf 0
报错信息:

下是过渡态的关键词
crest mtdTS1-2.xyz --shake 1 --noreftopo --cluster --chrg 0 --uhf 1 --cinp .xcontrol.sample
.xcontrol.sample
$constrain
atoms: 5,8-10
force constant=0.5
reference=coord.ref
$metadyn
atoms: 1-4,6,7,11-90
$end

Please check your input and, if present, crestopt.log.
(crestopt.log是空的)
谢谢各位老师,麻烦了。
