After I configured the files, there was a error.

Is it possible your problem is the same as this one? antmicro/gerber2ems#12

From the error messages, it seems that one or more of the output files are getting truncated after outputting time and aren't outputting a current or voltage value. Not sure if this is something that is more likely to happen when using gerber2ems.
