HI,
Sorry for the problems.

For the @afni_R_package_install -shiny
The default repository is [cran.rstudio.com].
But if for some reason, you can't reach that, you may have to install separately with another repository.
You can do that manually in R with:

install.packages(c('shiny','shinydashboard','plotly','colourpicker','data.table','gplots','RColorBrewer'))

It should give you an option to select a mirror, and choose one that is close to you.

It looks like "shiny" is the one giving you problems. It requires openssl and depending on your operating system, you may need to install it separately.
Some versions of linux need to install it with apt-get or yum or whatever your operating system uses.
If you are on linux, try installing openssl first then rerun

@afni_R_package_install -shiny

or do it manually as above.

For the ClustExp_StatParse.py error, can you email me your table.csv?
send to justin.rajendra@nih.gov
It looks to be some sort of formatting error, but I can't tell from the message board post.

Thanks, Justin
