bash: samtools: command not found
This means that you have to install samtools
But it also looks like you have paired end data, for which you should use -1 and -2 rather than -U.
There is maybe also something wrong with the comma separated list with spaces.
@OP: Locate the folder where the samtools is installed. Add that folder path to your .bash_profile or .bashrc.
i did but it still appear command not found :(
- Please navigate to samtools folder where samtools executable is present and type
./samtools.If it works, then you have samtools binary - Once it works, then type
realpath samtools - Then type
echo $PATH
Output from realpath should be in path output.
How did you install samtools?
Did you add the directory in which you installed samtools to $PATH? Check if everything is alright with
echo $PATH
