Hello Branko, did the previous job that ended normally write the files
<outputName>.coor, <outputName>.vel and <outputName>.xsc?

Most importantly, what were the values of outputName and restartName? If
they are different, so will the prefixes of the "output" and "restart"
state files for the colvars.
