Dear WIEN2k users,

After crash of calculation due to power down of cluster something 
happened with some of my calculations. For example, I performed 
spin-polarized Fe96H calculation, there were about 20 iterations of the 
SCF-cycle, but after restarting the machine and then the calculation, it 
failed with error in lapw1.

Here is PBS output file:

I tried to find information about it in the UG and FAQ, but couldn't 
find anything. I suppose some files, necessary for WIEN2k, are 
incomplete, but I don't know which ones exactly. What should I check 
first to restart the calculation correctly? Maybe specific options 
should be used in runsp_lapw? I started SCF by the following command: 
runsp_lapw -p -NI -ec 0.0001 -cc 0.001 -i 200.

Could anybody help me please? Thanks in advance.
