</span>does this happen also if you do not specify anything for<br>
nproc_ortho (or nproc_diag, they are the same), or if you<br>
specify nproc_ortho=1, in the command line for projwfc.x?<br>
<br>
It is possible to run most calculations done by projwfc.x<br>
using distributed matrices and parallel diagonalization. This<br>
is useful for large systems where Nband*Nband matrices may be<br>
very large and not fit into memory.<br>
<br>
This possibility however does not exist for case "tdosinboxes".<br>
Likely there is no need to stop the code, though. Just modify<br>
the part of code listed below and try:<br>
IF ( tdosinboxes ) THEN<br>
IF( nproc_ortho > 1 ) THEN<br>
CALL errore ('do_projwfc', 'nproc_ortho > 1 not yet<br>
implemented', 1)<br>
ELSE<br>
CALL projwave_boxes (filpdos, filproj, n_proj_boxes, irmin,<br>
irmax, plotboxes)<br>
ENDIF<br>
ELSE<br>
...<br>
ENDIF<br>
