Making bam files in Pysam

[ffinkernagel]

Do you have write permissions it this directory?

I have made a script that should generate bam files with the help of Pysam. But the problem is that that code does not work.

The mistake in the code is somewhere in the following code:
=============================================

inputSamFile = pysam.Samfile(inputBamFile, "rb")
outputSamFile = pysam.Samfile(outputBamFile, "wb", template=inputSamFile)
============================================

When I run this code, the following error message is generated:
===============================================

[martijn@animal provisional]$ python DPBamFileMaker.py TCGA-A6-2672-10A-01W-0833-10_SOLiD.bam man.bam
Traceback (most recent call last):

File "csamtools.pyx", line 609, in csamtools.Samfile._open (pysam/csamtools.c:6330)
IOError: could not open file `man.bam`
==================================================

I don't understan this error.

What am I doing wrong in this code? Can anyone tell me?
