I'm trying to run kraken v.1.1.1 to perform an analysis of metagenomic data, but when I try to give the

kraken-build -standard --threads 20 --db MY_KRAKEN_DATABASE

command, the following error appears:

Downloading taxonomy tree data ... rsync: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

The program was installed with conda, I tried to install kraken2 to check if it was the program version, but the same error occurred. I'm new to bioinformatics and programming, if anyone can help me solve this problem, it would help a lot.

Complete error:

Downloaded taxonomy tree data

Uncompressing taxonomy data... done.

Untarring taxonomy tree data... done.

Step 1/3: performing rsync dry run...

Rsync dry run complete, removing any non-existent files from manifest.

Step 2/3: Performing rsync file transfer of requested files

rsync: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

rsync_from_ncbi.pl: rsync error, exited with code 127

Try to install libiconv package by typing conda install -c conda-forge libiconv

The moment you sent this message, I installed libsconv with conda and it worked, he downloaded this part, however, now another error has appeared, related to ncbi:

Did you try using option --use-ftp

kraken-build -standard --threads 20 --db MY_KRAKEN_DATABASE --use-ftp ?
