<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Dear all<br><br>I have the following system. Substrate with 3696 particles and 4 polymer chains with 45 beads/chain. After typing g_gyrate, I have the following option:<br><br>Group 0 ( System) has 680 elements<br>Group 1 ( ZZZ) has 500 elements<br>Group 2 ( AAA) has 45 elements<br>Group 3 ( BAA) has 45 elements<br>Group 4 ( CAA) has 45 elements<br>Group 5 ( DAA)
has 45 elements<br>Select a group:<br><br>Can someone tell me how can I calculate the average radius of gyration
only from the groups 2,3,4,5 of the previous system? <br><br>Thanks in advance<br>Chrysostomos<br><br></td></tr></table><br>
