Hi again,
I have now successfully updated afni to version 16.2.09 using the -local_package method. The binaries from the page was updated even though the version displayed on the page was old.
Regarding the proxy problems: We have had some problems accessing the afni pages, such as the function help pages and this message board. When trying to get to an afni page it takes forever but eventually the page loads. It is better now but we have had issues. I'm not sure if the issue is with our proxy our if your page is proxy hostile... :). Other pages works fine though and we did have the wget problem. Might be worth looking into!
Thanks!
Robin
