Hello,

long ago I had a case when HG1 etc. were interpreted as mercury by phaser.

Could that be relevant to your case?

I hope not.
However, as I have already seen EPMR handle some Hydrogen as Carbon,
I am ready to see anything happening! :(

I will have a quick look to see if I can make Phaser
output atom numbers from what was read from the PDB.

Hello,

I have 4 molecules.
If I use Phaser's AUTO_MR with all default parameters on them,
I get the following scores:

        no_modif remove_H
molecule RFZ TFZ  RFZ TFZ
1        6.9 9.6  7.0 9.4
2        5.2 5.9  5.4 6.2
3        4.2 4.5  4.7 5.2
4        4.9 6.8  5.2 6.7

Hence, here are my existential questions, given that I heard
many times "H is transparent for X-rays":
* should I always remove H before running Phaser?
* why?

Here are a few lines of one of my PDBs containing H, in case it is
misinterpreted by Phaser:
---

Thanks a lot,
Francois.
