Hi,

I encounter the error in processing one of my MPRAGE brain image.

        MRInormalize: could not find any valid peaks

I found the previous post suggesting to add the -no1d option, but it
doesn't work, the same error message.

I use the 2004 snapshot version on Fedora Core 3, getting successful
results on other images but this one.

Another suggestion was to check the talairach.xfm. Should I use the
MNI tools for this problem? I figured I can live without the tools,
especially after having no luck with installing them...

Are there any workaround for this, and which part of the documents
should I read to understand the nature of this "valid peak" problem?

Best regards,
