instead of just alpha carbon as sphere. Could you please help me with this issue ?

Hi Ruchika,<br>
Assuming you are using Chimera, we recommend sending such questions to chimera-users@cgl.ucsf.edu (CC'd here) or else they may fall through the cracks.<br>
<br>
It doesn't make sense to me that you would need to show the sidechain. I can only guess that maybe you're showing ribbon and that is causing the confusion.<br>
<br>
If you are showing ribbon, you cannot see or select the alpha-carbon with the mouse, because ribbon normally hides the backbone atoms. If you select the ribbon it selects the whole residue. If you want to show backbone atoms at the same time as ribbon, use
command "ribbackbone" or alternatively, just hide the ribbon, and then show whatever atoms you want. Select only the CA and then change it to sphere.<br>
<br>
Explanation of "ribbackbone"<br>
<<a href="http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/ribbackbone.html">http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/ribbackbone.html</a>><br>
<br>
Example commands:<br>
open 1gcn<br>
ribbackbone<br>
show :5@CA<br>
repr sphere :5@CA<br>
<br>
I hope this helps,<br>
Elaine<br>
