Re^2: Asterisks instead of numbers in outs

Hi,
thanks for replay, dear Alex.
1) How to find out, what it is necessary to remove? Experimentally? Whether occurrence of this quasi-linear dependence means, that basis set is bad?
2) Whether somebody knows the program which can read FF's punch files?
  Thanks,
          Vyacheslav

>>Hi,
>>at use of rather big basic sets (VTZ2PD Valence Triple Zeta + Double Polar. + Diffuse on All Atoms) I have a regular bug in out files - asterisks instead of numbers:

>>It is impossible to open in ChemCraft about a quarter of out files. The same is for ANO-RCC (even in the greater degree), etc.

>>PS. Last days the number of out files with asterisks has approach to 100%...
