这是我一直在尝试的
def test():
import sys
import subprocess
file1 = open(sys.argv[1],"r") #this is the input to fastacmd
idx = file1.readlines()
outname = idx[0].split("\r\n")[0]
foutname = outname + "_f_output"
astaseq = subprocess.call(["fastacmd","-i", file1, "-o",foutname])
blastresult = subprocess.call(["blastp", "-db", "db1.faa", "-query", foutname, "-out", outname])
但是我被这个抓住了,我真的无法理解它
File "test.py", line 16, in <module>
fastacmd_blastp()
File "test.py", line 11, in test
fastaseq = subprocess.call(["fastacmd","-i", file1, "-o",fastaoutname])
File "/usr/local/lib/python2.7/subprocess.py", line 486, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/local/lib/python2.7/subprocess.py", line 672, in __init__
errread, errwrite)
File "/usr/local/lib/python2.7/subprocess.py", line 1202, in _execute_child
raise child_exception
TypeError: execv() arg 2 must contain only strings
任何人都可以帮忙吗?谢谢
