Hi,
I believe I've found a problem with the printing of the overlap integrals. As suggested by [1], I tried both print "ao overlap" and print "overlap".
While the "overlap" version is more concise, it appears to be missing several non-zero entries (e.g. #1-#2 overlap of ~0.25):

The "overlap" printing is missing some matrix blocks since they are symmetry equivalent to others (that should be printed).
Anyhow, if you apply the patch below, all the element will be printed
http://www.nwchem-sw.org/images/Print1e.patch.gz
Here are the instructions for applyin the patch:
cd $NWCHEM_top/src
wget http://www.nwchem-sw.org/images/Print1e.patch.gz
gzip -d Print1e.patch
patch -p0 < Print1e.patch
cd ddscf
make
cd ..
make link

| Thanks for link to the patch. I agree that the some matrix blocks will not be printed if they are either symmetry equivalent or really small. However, both #1-#2 and #2-#1 are missing despite being ~0.25.
