# BDSS configuration file

First, we create a bdss configuration file `bdss.cfg` in the current directory.

```{r}
system('echo "[metadata_repository]" > bdss.cfg')
system('echo url=http://bdss.bioinfo.wsu.edu/ >> bdss.cfg')
```

# Download data

```{r 'download and extract reads'}
# create a directory to store read files
dir.create('read_files_directory')
# download and extract reads
urls = strsplit(gsub(',', ' ', 'URLS'), ' ')[[1]]
urls = urls[urls != '']
# loop through SRA accessions to download and extract reads.
for(url in urls) {
    # bdss_command = paste0('cd ./read_files_directory && /tool_deps/_conda/bin/bdss transfer -u ', url)
    bdss_command = paste0('cd ./read_files_directory && /main/sites/galaxy/galaxy/tools/_conda/bin/bdss transfer -u ', url)
    print(system(bdss_command, intern = TRUE))
}
