GithubWangYang commented 4 years ago

in my ctl file, the tdef unit is 'mo', when i run the script. throw a error like 'Cannot get a common metadata divisor for NumPy datetime metadata [s] and [M] because they have incompatible nonlinear base time units' the numpy's arange can not support month or year.

Can you just paste all the ctl content here so I can get a quick fix?

Thank you for using the package and finding this bug. I've fixed it. So now you can parse your ctl correctly. Please tell me if it works fine in your case.

Another big problem is that the current version does not support PDEF, as in your case. I would love to enhance (see here #5) that but I do need some time. Would you please send me your associated binary data file if it is not too large? email: miniufo@163.com or qq: 176427777.
