Error of older 2020 version of SRA toolkit
fastq-dump & prefetch will save the downloaded .sra files in
$HOME/ncbi/public/sra/
Change the default SRA download directory by using vdb-config
prefetch --verbose ERR481290
"path not found while resolving tree within virtual file system module"
Problem:
'HOME' variable might have changed (compared to installation of SRA-tools)
echo $HOME
/home/my-user-name/
Solution:
Set SRA-tools config to default values (confirm new HOME directory):
vdb-config -i
# if path is correct, just confirm again by typing numbers: 6 and 7
https://github.com/ncbi/sra-tools/wiki/Toolkit-Configuration
# check setting file in your home directory (file generated by vdb-config)
cat ${HOME}/.ncbi/user-settings.mkfg
