<div>As Donald explained, MRtrix on Windows is compiled as a 32-bit executable. A default 64-bit Windows installation will only allow you to address 2 GB of ram (<a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx" target="_blank">http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx</a>).
This is why streamtrack fails as soon as your file reaches 2GB of size. </div>
<div><br>
</div>
<div>
<div>A 64-bit Windows executable would solve this issue, but unfortunately I haven't been able to get the visualization part of mrtrix working properly in a 64-bit version on Windows...</div>
<div><br>
</div>
</div>
<div>Currently, the only way around this is to use the 64-bit Linux or MacOS version.</div>
<div><br>
</div>
<div>Hopefully, future releases will include a 64-bit version on Windows.</div>

<div>Hi Donald,<br>
</div>
thank you for your answer. I am working on SSD formatted in NTFS with 16G of RAM and the size of the file is around 2G. So I have no idea about this issue.<br>
</div>
Cheers<br>

<div dir="ltr">Hi Matteo,
<div><br>
</div>
<div>Sounds to me like you've hit a file size limit. What is the size of the tracks file when it fails? It might be due to the 32-bit 4GB boundary (MRtrix on Windows is compiled as a 32-bit executable, as far as I know), but it could also be due to a limitation
of your filesystem. Are you writing the tracks to a NTFS partition, or a FAT partition? If the latter, you'll definitely encounter issues like you describe...</div>
<div><br>
</div>
<div>Hope this helps,</div>
<div><br>
</div>
<div>Donald.</div>

<div>Dear MRtrix experts,<br>
</div>
I tried to use streamtrack SB_PROB to obtain the whole brain tracking to fed into the TDI processing (so more than 1 million fibers). Every time I got this error: "973180 generated, 772168 selected [ 19%]streamtrack: error writing to tracks file: Invalid
argument". I tried to change data but i had the same problem and it always stops around 18 percent. I am using MRtrix on win 7 64b.<br>
</div>
Thank you very much!<br>
