Body
<p>Sorry if this question is dumb. I am using python <code>subprocess</code> statement to call a .bat file in Ubuntu (Natty 11.04), however, I got error messages:</p> <pre><code>Traceback (most recent call last): File "pfam_picloud.py", line 40, in <module> a=subprocess.Popen(src2, shell=0) File "/usr/lib/python2.7/subprocess.py", line 672, in __init__ errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1213, in _execute_child raise child_exception </code></pre> <h3>run this python file</h3> <pre><code>$python pfam_picloud.py </code></pre> <h3>Python code (pfam_picloud.py)</h3> <pre><code>#!/usr/bin/python # met="wTest.dvf" run="run_pfam.bat" inp="pfam_input.PFA" import os import stat import shutil import subprocess import string import random # Generate a random ID for file save def id_generator(size=6, chars=string.ascii_uppercase + string.digits): return ''.join(random.choice(chars) for x in range(size)) name_temp=id_generator() cwd=os.getcwd() src=cwd src1=cwd+'/'+name_temp if not os.path.exists(src1): os.makedirs(src1) else: shutil.rmtree(src1) os.makedirs(src1) ## shutil.copy(src+"/"+run,src1) shutil.copy(src+"/"+met,src1) shutil.copy(cwd+"/pfam_pi.exe",src1) shutil.copy(src+"/"+inp,src1) # src2=src1+"/run_pfam.bat" os.chdir(src1) a=subprocess.Popen(src2, shell=0) a.wait() </code></pre> <h3>bash file (run_pfam.bat)</h3> <pre><code>#!/bin/sh ./pfam_pi.exe pfam_input.PFA </code></pre> <p>I can successfully run this bash file in Ubuntu. So I guess, I messed up something in my Python script. Could anyone give me some suggestions? Thanks for any inputs.</p> <h3>EDIT</h3> <p>the file <code>pfam_pi.exe</code> is a Linux executable. I compiled it in Ubuntu. Sorry for the confusion.</p> <h3>update</h3> <p>Well, I got different types of error now. 1. With <code>#!/bin/sh</code>, it said <code>No such file or directory</code>. 2. With <code>/bin/sh</code>, it said <code>exec format error</code>. 3. If I sent everything as arguments <code>a=subprocess.Popen(['./pfam_pi.exe', 'inp', 'src1'], shell=0)</code>, it said <code>end of line symbol error</code></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
