Hi ,<br>I just put my pga,pgv in *_dat.xml file,and&nbsp; $net-&gt;id equals none of the four netid like CIIM,DYFI etc.At this moment,the variables like <br>@$ions,@$ilats should be empty,and how does grind convert intensities to PGM/PSA&nbsp; withou my giving intensities? It seems that grind will use Wald99.pm (if i use it ) to do that,am i right? i was confused about it!<br><br>Thanks,<br>WSC<br><br>
