Rscript execution error

[Raina-M]

I installed Merqury (v1.3) through conda. After running merqury under conda environment:
merqury.sh $WD/Carex_hic.meryl $REF Carex_pctg
I got the most expected outputs such as qv, completeness, and hist files, but no plots were generated. After checking the log file, I found the error:

For 86366741 distinct 20-mers (with 24 bits used for indexing and 16 bits for tags):

Rscript execution error: No such file or directory

So for some reason, merqury could not find Rscript, but if I run which Rscript, I got:
/PATH/bin/conda-envs/envs/merqury/bin/Rscript
And I also ran Rscript ./plot_spectra_cn.R
I got the same error as following:
Rscript execution error: No such file or directory

Please refer to this: #49 (comment)
and see if this fixes the path issue.
Also, try echo $MERQURY and see if that prints the right path.

The plot_spectra_cn.R could be run separately with

Rscript $MERQURY/plot/plot_spectra_cn.R --help

Sorry for the hassle!

Hello, thank you for the reply!

echo 1 in util.sh did not fix the problem. I got the same error message.
And echo $MERQURY printed the right path.

Running plot_spectra_cn.R separately could derive the plots but I had to deactivate conda environment at first, otherwise, I still got an Rscript execution error.
