[Samtools-help] Tabix issues

[Jake C. <jc...@st...>]

When attempting to run tabix from a python program in eclipse ide, my
program throws errors.  Python version is 2.6, tabix version is 0.2.5,
running on Windows 7.  The errors thrown are as follows:
 File "C:\Users\jcc7\workspace\GeneZoom\src\genezoom.py", line 113, in main
    vcf = vcfReader( options.vcf_file )
  File "C:\Users\jcc7\workspace\GeneZoom\src\vcfutils.py", line 75, in
__init__
    self._vcf = tabix.Tabix(filename)
  File "C:\Python26\lib\tabix.py", line 50, in __init__
    self.tabix = tabix_init();
  File "C:\Python26\lib\tabix.py", line 32, in tabix_init
    tabix = load_shared_library('tabix')
  File "C:\Python26\lib\tabix.py", line 22, in load_shared_library
    candidates = glob.glob(_path+'/lib'+lib+suf);
UnboundLocalError: local variable 'suf' referenced before assignment
Exception AttributeError: "Tabix instance has no attribute 'tabix'" in
<bound method Tabix.__del__ of <tabix.Tabix instance at 0x034A91C0>> ignored

genezoom.py is my own program, which attempts to define a vcfReader through
vcfutils, by using tabix.  But the error is within tabix itself, in the
following code:
def load_shared_library(lib, _path='.', ver='*'):
    """Search for and load the tabix library. The
    expectation is that the library is located in
    the current directory (ie. "./")
    """
    # find from the system path
    path = find_library(lib)
    if (path == None): # if fail, search in the custom directory
        s = platform.system()
        if (s == 'Darwin'): suf = ver+'.dylib'
        elif (s == 'Linux'): suf = '.so'+ver
        candidates = glob.glob(_path+'/lib'+lib+suf);
        if (len(candidates) == 1): path = candidates[0]
        else: return None
    cdll.LoadLibrary(path)
    return CDLL(path)

The error thrown is due to the fact that I am running Windows 7, and not
using a Darwin or Linux operating system, thus "suf" is never initialized.
Is there a way to get this to work, or is there a link to a Windows-viable
version (did I just accidentally download the Mac/Linux version instead of
the Windows version)?
