Error: err: option file. add space around the equal sign?.

I keep getting this error while trying to run codeml on my alignment:

Error: err: option file. add space around the equal sign?.

I thought it was about the length of the directory but I shorted it a lot and the error is still popping out.

Does anybody know where is this coming from?

Thanks!

software error codeml

It suggests it may be in your options file. Please share your input files and your exact command. There isn't enough information in your post at the moment.

I don't know CodeML that well myself, but I'd infer from that error that you have an options file which is supposed to look something like

option1 = xxx
option2 = yyy
option3 = zzz

but yours probably looks something like

option1=xxx
option2= yyy
option3 =zzz

And it expects the = sign to be surrounded by whitespace.

Hi, have you got you problem resolved? I also came across the same error, could you please give some suggestions?
