<div>Hi Tom</div>
<div> actually i calculated the cavity inside my protein through voidoo and it gives me a map. so i was trying to see residues lining the cavity. i was not aware that voidoo gives us list of atoms lining the cavity in its log file. any way i looked in the log file and found the residue. i manually selected the residue (about 100) and make the figures. but it is nice if i can do it by computers without typing the resid of about 100 residue.

<div>Thank you.</div>

<br>point? That would would include all the atoms near the map, even those<br>far from the portal. Do you also want to restrict to 3.2A of the<br>portal? How do you define that? Does it mean 3.2A from the z axis<br>(treating the portal like a straight line)? Or have you already limited
<br>the selection to ions in the channel and you just want to know which of<br>them is within 3.2A of the contour surface?<br><br>Please describe your problem in more detail.<br><br>There is a tool on the Chimera experimental features page that you can
