Another question: does the option to open/display the whole map would also work when using the open command to load the volume and without touching the Volume display dialogue? I am using a script to open and fit several
<span style="font-size:12pt">coordinates models with minimal or no GUI use.</span></div>

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Also I did notice that if the map is opened/displayed as a single plane then the <fitmap> command does not work as intended. It appears as is the model is fitted to an empty map. A workaround I found was to crop the map before fitting using the command <volume
#map region ...>. The cropped map always seems to show all the planes (due to the smaller size?).<br>

Dear Hernando,<br>
<br>
(1) there is a setting for what size is shown as a plane. In Volume Viewer menu, choose Features... Data Display Options. That shows more options in the Volume Viewer dialog. In those options you can turn off (or change the size) for<br>
<br>
"Show data when opened if smaller than [size] Mvoxels"<br>
"Show plane when data larger than [size] Mvoxels"<br>
<br>
See data display options:<br>

<br>
Then you can save those settings in your preferences (so they will be used in the future) using Volume Viewer menu "Features... Save default dialog settings"<br>
<br>
(2) for map-map fitting, the "fitmap" command has an "envelope" option of whether to use only the grid points in the fit map with values above the contour level in Volume Viewer. This option is default true but you can set it false to use all nonzero-valued
grid points. See fitmap options:<br>

As far as I know, display step size does not affect the calculation.<br>
<br>
I hope this helps,<br>
