problem in conversion sra to fastq

I wrote code:

#Import the data table into a variable
$sorceFolder= import-csv 'elife-526-s.csv'
$files=$sorceFolder|select SRA
#Convert any SRA file to fastq
$list = $sorceFolder |where {$_."SRA" -eq "ERR1654119"}
foreach($f in $list){
prefetch $f --max-size 100G --progress -O C:\Users\user\Desktop\labHebrew\RhizosphereMicrobiome\Data
fasterq-dump --split-files --threads 32 --stdout $f -O C:\Users\user\Desktop\labHebrew\RhizosphereMicrobiome\Data
}

And I got a comment:
