I can't seem to get the --inverse switch to behave in cmtk 2.2.6


Incorrect syntax or bug?

Thanks,

Greg.

Ah, if all problems were but this simple... :)

The "--inverse" parameter is not parsed the same way as other command line options (because it is, strictly speaking, part of the xform sequence).

So what you need to do is insert "--" before it -

/opt/local/bin/streamxform -- --inverse /Volumes/JData/JPeople/Common/Neuroanatomy/BridgingRegistrations/JFRC2_IS2.list

In general, "--" denotes the end of the non-positional arguments, regardless of whether anything that follows also starts with a hyphen (that's actually pretty POSIX I think).

Best,

Hi Torsten,
Originally posted by Torsten Rohlfing:
That works fine. Thanks for the tip. On the other hand, there is no indication from --help or --help-all that this extra -- is specifically required when using the inverse switch. I've been using CMTK for years and didn't get it (POSIX or not). Would you have a suggestion to clarify the docs for that?

Best,

Greg.

Well, I certainly agree it would be a good idea to have this documented explicitly. I am just not entirely sure of the best way, technically, to do that.

Maybe you can file a feature request and I'll see whether there's a good solution when I have some time.

Thanks.

Okay, so it turns out the syntax for the xform sequence was actually coded separately in each tool that uses this construct.

So I just added a note regarding the use of "--" before the first xform in the sequence to each of the tools.

This is in svn r/4701; not sure when I'll ever get to releasing CMTK 2.3.0, but it will be in there as well.
