<span style="font-size: inherit;">The file </span><span style="caret-color: rgb(0, 0, 0); font-size: inherit;">HU2mat.txt displayed in GATE erro<span>r message is a "look-up table" used by GATE to convert each range of HU values in your CT image into tissue/organ
material defined in the GATE material database. So error is saying that there are some HU values in your CT image that are defined in the <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;">HU2mat.txt.
You have two options, whether reacaling the HUs values in your CT images according to the HU values in the <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;">HU2mat.txt. Or modifying
the later by adding the out of range HU values in your CT image and adding it to the <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;">HU2mat.txt. </span></span><span></span></span></span></span></div>

<div dir="ltr">Dear Gate users,<br>
<div>I want to run a simulation with a CT images, but I've got the following error:</div>
<div dir="ltr"><br>

<div>--------<br>
</div>
<div><!> *** WARNING *** <!> The image contains HU indices out of range of the HU range found in /home/med/Linac_ap15_9m/data/patient-HU2mat.txt<br>
HU min, max: -1001, 3001<br>
Image min, max: -1000, 3071<br>
<br>
[Volume-0] ERROR: too many HU values are out of the range of the materials table:
<br>
******** 0 underflows (HU<-1001) ******** <br>
******** 89 overflows (HU>3001) ********<br>
[Volume-0] (The maximum 'bad' fraction is 0 and the image has 20709376 voxels, <br>
so maximum 0 out-of-range HU values are allowed.<br>
Possible solutions: fix your input image, or expand the HU range of the HU-to-materials table.
<br>
Or, if you really know what you are doing, you can set the 'setMaxOutOfRangeFraction' option to a nonzero value larger than 4.29757e-06 .)<br>
