Reidentify can’t open id file in database

I'm trying to revise a wavelength calibration I did a few years ago. I've copied both data and database from cd to disk, and tried to run reidentify. It allows me to fit one line, then tells me it can't open the id file in the database.

As far as I can see there are no problems with permissions, the file exists and is readable. What's going wrong?

Problem solved: it turns out it was the permissions after all. A swift chmod u+w did the trick.
