Dear Dianne,

Just a quick follow-up to announce that I have hosted the application on a webserver I am renting and this is now up again. You'll find the working application at the following address:
http://www.emmanuelcaruyer.com/q-space-sampling.php

The associated article has been published by MRM, and the author manuscript is accessible online at the following address: http://hal.inria.fr/docs/00/82/16/88/PDF/article.pdf

Thanks again for you feedback!

Best,
Emmanuel.

Dear Dianne,

Thanks a lot for your positive feedback! I'll do my best to keep this webpage up-to-date and maintain it as best as I can. I will let you know when the application is up and running again.

Best,
Emmanuel.

Dear Emmanuel,

Thankyou so much for your response and explanation!  I am not in need of a gradient table immediately, so I'm happy to wait! I was mostly just really impressed by the webpage and thought it would be a great educational resource.

Dear Dianne,

I have recently moved from Inria (France) to University of Pennsylvania, and I am migrating this web application from Inria web servers to UPenn. Unfortunately some features are still broken and I am working on bug fixes with the web admins here. This is the reason why you are not able to download gradient tables from the tool.

But if you want I can generate a sampling scheme for you using this method. All you would need to send me are the number of sampling shells, their b-values, and the number of gradient directions on each shell. I'll also need to knwo whether you need an incremental scheme or not.

Last note, my scripts are written in Python and I am willing to distribute my code. This should be available in Dipy in the near future. But if you are comfortable with Python and Numpy/SciPy, I can as well provide you with the source code.

Please let me know what is best for you and your team.

Best regards,
Emmanuel.

Dear Dr Caruyer,

I just visited your fascinating webpage:


However, I was disappointed to find that when I clicked the download button, 
nothing seemed to download.

I have tried both safari and chrome, but neither seems to help.
Another researcher has recently reported the same problem on the FSL listserve 
(he tried firefox as well)

Can you help us?

Thankyou,

Dianne
