Thank Michael Dondrup, joe and 5heikki very much.
As you all suggested I re-install MUSCLE. The way 5heikki told me really works, and I don't know if conda works.
Thanks again.
I come across a question when running the multiple sequence alignment program MUSCLE.
My operation system is win10, with a WSL, ubuntu LTS 18.
I download the MUSCLE program , and run the command.
tar -zxvf muscle3.8.31_i86linux64.tar.gz
mv muscle3.8.31_i86linux64 muscle
chmod +x muscle
Then I run the program,
muscle
but an error ocurrs, "segmentation fault (core dumped)".
This problem often ocurrs due to the limited memory. However, I just run "muscle" with zero input. The same problem still happened when I test a only 100 byte fasta file.
Any one has a suggestion? Thank you sincerely.
It also failed on Ubuntu LTS 20.04 on WSL2, however this worked:
mkdir muscle
cd muscle
wget https://www.drive5.com/muscle/muscle_src_3.8.1551.tar.gz
tar xzvf muscle_src_3.8.1551.tar.gz
make
./muscle

Possibly, installing muscle from the ubuntu repository or compiling the software from source might help.
