Hi Dietlind,<br>
Of course I remember you! And thanks for the kind words about Chimera, they mean a lot!<br>
<br>
Well, it is a limitation of line rendering… the computer can only draw them up to a certain thickness, and with supersampling (default 3x3) it is trying to make the whole image much larger and then sample it down to the final requested size. The dialog opened from menu: File… Save Image should report the “effective maximum line width" given its current settings. That message appears at the bottom of the dialog for several seconds after it’s been opened.<br>
<br>
If you are showing the pseudobonds as lines, the only ways to get them a little thicker in the final image is to decrease the final pixel dimensions and/or the amount of supersampling. When I ran across this issue for journal figures I ended up using 2x2 supersampling, which was quite satisfactory. You might even try turning off supersampling (1x1) and seeing if the final image is good enough. I agree the limitation is bothersome, however. It’s mentioned a little bit here:<br>
<<a href="http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/print.html#supersampling" target="_blank">http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/print.html#supersampling</a>><br>
<br>
If that doesn’t give sufficient fatness, however, another possibility is to show the pseudobonds as sticks instead of lines. You could change them to sticks in the pseudobond attributes opened from the PseudoBond Panel or in the Selection Inspector, or with a command like:<br>
<br>
setattr p drawMode 1<br>
<br>
(0 is wire, 1 is stick) and adjust radius (again in either of the aforementioned dialogs) or with a command like:<br>
<br>
setattr p radius .1<br>
<br>
Default radius is 0.2, which might be too fat. I hope this helps… happy to provide more details or tips if you get stuck!<br>
Best regards,<br>
Elaine<br>
