With the changes that I am about to commit it now works. It only required a small update.

updated the example and test script to use elecpos instead of pnt, made the representation of the boundaries and the conductivity consistent (they were the other way around) mac001> svn commit Sending external/openmeeg/om_write_cond.m Sending external/openmeeg/openmeeg.m Sending external/openmeeg/openmeeg_eeg_leadfield_example.m Sending external/openmeeg/testOpenMEEGeeg.m Transmitting file data ....
