Several options:

1. In the validation GUI, the real-space correlation tab will have
statistics for individual residues (you just need to lower the CC
cutoff, and in the nightly builds there should be a button to dump the
entire unfiltered table to a file).  The multi-criterion plot will
show the B-factor along with CC and map levels (and validation

2. In the main GUI, under "Other tools", "Display ADP statistics" will
essentially do what that pdbtools command does.

3. In the same place, "Plot average B-factors in PDB file" will do
exactly what it says.
