<p>Hi,</p>
<p>the image size in MB does not really matter. It's more about the
resolution, where too small voxel sizes might be a challenge.
Usual resolutions range between 0.75 to 1.0 mm.</p>
<p>Increasing the vertex density makes the mesh larger, thus the
simulations slower but more accurate. Just try out the suggested
increase to see whether your problem is resolved.<br>
</p>
<p>Best regards,</p>
<p>Axel<br>

<div>What can be done for this?</div>
<div><br>
</div>
<div>Also, I wanted to know if structural MRI images above 45 MB
can be processed without any errors as i mentioned above. But
I have processed T1 weighted structural MRI image having a
size of 38MB. is having the above error.</div>

</div>
<div>I want to know what is the minimum criteria for the T1
weighted MRI image's size. </div>

<div>Runtime error suggested increasing vertex density to 1.0.
(-V).. What is the consequence of increasing vertex density on
electric field strength distribution?</div>

<div>Waiting for the help. </div>
