Hi @Soha,

It's been a while since we've seen the dreaded [`0x8` error](https://forum.qiime2.org/search?q=0x8%20memory%20not%20mapped). I notice you are running 2017.12 which had an early release with this issue.

Could you provide the results of `qiime info`? You may just need to update to the latest QIIME 2 (in fact I would recommend that in either case!)

Otherwise, do you have an RStudio installation alongside QIIME 2 (or any other installation of R)? The library paths are known to conflict with each other causing this issue as well. In that case use:

```auto
echo ".libPaths(.libPaths()[2])" > ~/.Rprofile

```

to correct the problem, although this will come at the cost of RStudio's packages.
