<P DIR=LTR><SPAN LANG="en-ca"><FONT FACE="Calibri">I have been working with a very large structure of many subunits, the E.Coli Ribosome particle with the Signal Recognition Particle attached (PDB 2J28)</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-ca"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-ca"><FONT FACE="Calibri">I</FONT></SPAN><SPAN LANG="en-ca"> <FONT FACE="Calibri">was able to</FONT></SPAN><SPAN LANG="en-ca"><FONT FACE="Calibri"> create an image of the SRP part of the complex. I selected that subunit.</FONT></SPAN><SPAN LANG="en-ca"><FONT FACE="Calibri"> And</FONT></SPAN><SPAN LANG="en-ca"> <FONT FACE="Calibri">was able</FONT></SPAN><SPAN LANG="en-ca"> <FONT FACE="Calibri">to hide all the other subunits. So with the subunit selected I tried to visualize</FONT></SPAN><SPAN LANG="en-ca"> <FONT FACE="Calibri">only that image</FONT></SPAN><SPAN LANG="en-ca"><FONT FACE="Calibri"> as a surface. Wouldn</FONT></SPAN><SPAN LANG="en-ca"><FONT FACE="Calibri">’t let me, getting an error message that it was too large and I should somehow split it. Don’t know how to do that.</FONT></SPAN><SPAN LANG="en-ca"><FONT FACE="Calibri"> I know the whole dataset is very large, but the SRP portion is only 400 amino acids.</FONT></SPAN><SPAN LANG="en-ca"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-ca"><FONT FACE="Calibri">A work around would be if I could somehow select the SRP subunit and have it as a dataset to reload as that subunit alone. Then not so big. Don</FONT></SPAN><SPAN LANG="en-ca"><FONT FACE="Calibri">’t know how to do that either.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-ca"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-ca"><FONT FACE="Calibri">Your suggestions. I couldn’t find anything in the tutorials that might help. </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-ca"><FONT FACE="Calibri">I was able to show the surface of another PDB file that was much smaller.</FONT></SPAN></P>
