<div><span></span>Hi Elaine,</div><div>Thanks for your help. </div><div>I have changed the model and now it works. The .dx file is #1. </div><div>So I use the command: <span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">measure fieldLines #1 lines 500 startAbove 10 color pink linewidth 2. </span></div><div><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">The command works but the field lines do not appear.</span></div><div>Is there any problem of the commands?</div>

<div>Your command looks OK to me, but are you sure that the dx file is model #0? Check in the Model Panel (open from Favorites menu) that it is really model #0. If you have other things open at the same time, like the atomic structure, it could be #1, #2, etc. instead and you should change the model number in the command. Other than that, my only other idea is that the dx file is empty or the wrong format.</div>
<div>I hope this helps,</div>

<div>> Hi</div>
<div>> I want to make the electric fieldline but there are always some problems.</div>
<div>> I did this as follows,</div>
<div>> 1. run add charge to the system</div>
<div>> 2. run APBS, the I get the electrostatic surface and a file named 1.dx</div>
<div>> 3. open 1.dx</div>
<div>> 4.measure fieldLines #0 lines 500 startAbove 10 color pink linewidth 2</div>
<div>> then I get the problem : no volume specified</div>
<div>> </div>
<div>> I have check the userguide of measure fieldlines, but there is nothing about the volume. </div>
<div>> measure fieldLines map-model(s) [ lines N ] [ startAbove cutoff ] [ step s ] [ modelId model-number ] [ color line-color ] [ lineWidth width ] [ tubeRadius radius ] [ circleSubdivisions M ] [ markers true|false ]</div>
<div>> </div>
<div>> what should I do next?</div>
<div>> Thanks.</div>
