<p class="MsoNormal">Hello Sebastien,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Thank you for your reply. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I have 2 files, 6 GB each.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">They are made with 2 different versions of Capture our Hi-speed recording software. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">We make use of the .fli format and we tried to be as compatible with the Bio-formats as possible.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Unfortunately, we could not work around the 12 bit, hence the unsupported data format.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Personally, I have tried to get bio-formats to compile on my one machine, I made a checkout, but I ran in too many problems. It seems that you are planning to have a new release.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Because I wanted to fix the problem of not being able to open files having a filesize bigger than 2 GB. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So could you take this in to account as well? To open our files virtual, FiJi supports this, right?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Is it okay for you if I share the files through Google Drive, as they are too big to upload to your server?<o:p></o:p></p>
