LCAO coefficients

It is possible to analyze LCAO coefficients in both the cluster and band calculations. In the cluster calculation, if a keyword, 'level.of.fileout', is set in 2, the LCAO coefficients are added into a file, *.out. As an example, LCAO coefficients of Methane.dat discussed in the Section 'Test calculation' are shown below:

In bulk calculations, if a keyword 'MO.fileout' is set in ON, LCAO coefficients at k-points which are specified by the keyword 'MO.kpoint' are output into a file *.out. For cluster calculations, 'level.of.fileout' should be 2 to output LCAO coefficients. But, for band calculations, the relevant keyword is 'MO.fileout' rather than 'level.of.fileout'.
