Hi,
Thanks for advice. It was a very convenient solution. However, my
inclusive mask does not seem to apply to 7 of my 12 subjects. Instead of
showing the proper mask (located in the ventral lateral premotor cortex),
Featquery displays the bottom EPI slice and lacks coordinates. I checked
log files and registration results in .feat-dir on first-level and they
seemed fine. Any idea on what may have gone wrong? I can upload the files
if needed.
Kind regards,
Benny Liberg
