Dear QE users:<br><br>A davcio error came up when I was doing Lowdin analysis using projwfc.x. I first carried out a scf calculation followed by nscf with a extended k-mesh and everything went smoothly. But when it comes to pdos calculation, the program crashed and kept saying the following error message:<br>
<br> Calling projwave .... <br><br> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br><br> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br> from davcio : error # 10<br>
error while reading from file<br> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br><br>I understand that davcio error is usually related to an I/O problem, but I do have appropriate permissions over all necessary files, and there is plenty of space on the disk. There was no problem when I was running example08 (the pdos example come with the PWscf package), so probably there are some problems caused by my own system.<br>
<br>This problem is killing me these days, and I will highly appreciate it if someone would take a look at it. By the way, I am taking care of a Cu-O system with a total atom number of 42, and I am using 4.2 version (parallel) PWscf. <br>
