<div dir="ltr">Hi Matteo,<div><br></div><div style>OK, 2GB is probably the limit in a 32-bit environment since file offsets will typically be stored using signed integers. Under 32-bit Linux this (usually) isn't an issue since these are actually stored using 64-bit quantities (at least if the kernel support large files, which is the case on any modern Linux distribution). My guess is the compiler used to build MRtrix on Windows still uses a 32-bit integer for file offsets... It's unfortunately not possible at this stage to provide a 64-bit build on Windows due to the difficulties in getting working GTK dependencies - Ben Jeurissen will probably tell you more about it if you're interested. All I can recommend is trying the Linux or MacOS version...</div>

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>
