Hi Folks,
Does anyone know of an accurate way to mine the PDB for what percent of
total X-ray structures deposited as on date were done using molecular
replacement? I got hold of a pie chart for the same from my Google search
for 2006 but I'd like to get hold of the most current statistics, if

Dear Raji,
the numbers you have accumulated might already be accurate, it is more
a question of how precise your numbers should be - and this might
become a long discussion without resulting in a single answer:
Take into account that the PDB query

From my own db program:
Number of entries in histogram: 711
Total number of instances : 78467
0 48249 0.6149 MOLECULAR REPLACEMENT
1 8557 0.1091 NULL
2 5632 0.0718 SAD
3 5128 0.0654 MAD
4 3600 0.0459 FOURIER SYNTHESIS
5 1762 0.0225 OTHER
6 1171 0.0149 MIR

Thanks to everyone who responded. I appreciate your pointing out the
caveats of such statistics mining expeditions.
I remember (with no accuracy or precision) sitting in a lecture by Wayne
Hendrickson years ago and watching him cringe at the notion of considering
the simple case of difference

The only way to really do creative stats on the PDB is to just
download the whole thing. It is a sobering thought to realize just how
tiny it is! Less than 17 GB. Once you've got it all on your hard disk
you can start writing little programs to look for different things. I

will check if the starting R factor is too high and just automatically
invoke a run of MR to see if something clicks.
