The error code and consensus argument look similar to a thread I stumbled upon trying to debug my own DADA2 issue, which can be found here: [An error was encountered while running DADA2 in R (return code 1), please inspect stdout and stderr to learn more - #5 by kkcool](https://forum.qiime2.org/t/an-error-was-encountered-while-running-dada2-in-r-return-code-1-please-inspect-stdout-and-stderr-to-learn-more/1938/5)
Not sure if this is exactly the issue you're encountering or a possible fix, but it's worth checking out.

Thanks @Brightbeard! That is actually a different error (`Input must be a valid sequence table.` vs `unused argument(method = "consensus")`, so that thread isn't really applicable to @ana_RODILES issue. Thanks!

@ana_RODILES, it looks like you have a different version of `R` and `dada2` that is overriding the versions that we provide with QIIME 2! This happens sometimes, [please take a look at this hack](https://forum.qiime2.org/t/rprofile-and-libpaths-with-dada2-exit-code-11/1519/3) to see if it fixes the issue for you.
Thanks! π¦

HΔ° Matthew,
Thank you for your reply. I have increased the mem to 500 gb and I change the TEMP directory to somewhere else with the following command.
```bash
export TMPDIR="/home/projects/pr_46704/people/argl/Projects/BioCat/Functional_guilds/Enrichments/ftp.cbs.dtu.dk/Arda/RawData/ftp.cbs.dtu.dk/Raw_Seqs/Temporary"
```
Then it started to analyse however, I got the following error afterwards.

Hi @thermokarst, many thanks for your reply. I have tried echo ".libPaths(.libPaths()[2])" \> ~/.Rprofile but unfortunately haven't work. After other advises I have also tried to download the last version of R 3.4.3 (outside of the qiime enviromment) and dada2 1.2.2 (inside of the qiime environment). However I got 'the same' error. Then I uninstall R outside of the qiime2 environment and I got the same error (below). Not very sure what else I can do. Any suggestions please? Many thanks!

I got this:
/home/mothur/.Rprofile
which is weird because we also tried to delete R, and apparently is still there... The previous person working on the server installed R and dada2... this why "/home/mothur". However my knowledge about virtual machines is scarce... but I'm suspecting some interactions of R dependencies.
I also tried yesterday with Atacama tutorial, in case the problem were because of the sample nature, but same error as usual, in DADA2 with R. Anyway there is something good, I tried today Atacama with Deblur following [Analyzing paired end reads in QIIME 2](https://forum.qiime2.org/t/analyzing-paired-end-reads-in-qiime-2/2021) and it worked (got table, sequences data and stats.qza!). So there is something working π
Thanks @thermokarst
Ps. QIIME2 have been also upgraded to qiime2-2017.11

This makes sense --- deblur doesn't use `R`, so it isn't implicated in all of this!

I don't think we want to get rid of anything in this file, it looks like exactly what it should be!
Can you report the results when running this command?
```bash
$ R -e ".libPaths()"

Hi @ana_RODILES, how about we remove your environment and try again? Specifically, can you run the following:
```bash
$ source deactivate
$ conda env remove -n qiime2-2017.11
```
Don't do anything to the `~/.Rprofile` file, we want that to stay right where it is, with the content it has right now.
Then, follow the [official install guide](https://docs.qiime2.org/2017.11/install/native/) to re-install. Let us know how it goes! π¦

Hi @thermokarst, when I applied those commands I got this:
Proceed ([y]/n)? y
WARNING conda.core.link:run\_script(516): pre-unlink script failed for package conda-forge::widgetsnbextension-3.0.8-py35\_0

CondaEnvironmentNotFoundError: Could not find environment: qiime2-2017.11 .
You can list all discoverable environments with `conda info --envs`.
So I proceed (Y) and I installed qiime 2 following the website again. And magic, dada2 works finally! I think the key was to uninstall qiime2 properly with the last commands you provided. Many thanks for your great help, @thermokarst!!!!!
