How can I install the PyAffy Python package under Windows 7?

Question

[Thomas.F.Hahn3]

I need to install the Python package PyAffy under Windows 7. It seems to be the only package, which can read in the .cel files, which are produced by Affymetrics's Yeast2 Microarray chip. But each installation fails because I keep getting the error message that the file named "vcvarsall.bat" is missing. This is a known bug.

Some people wrote that they managed to fix it by installing Visual Studio 8.0 SP1. I followed exactly their instructions but I could not get it to work. Could you please help me by explaining me what I need to do to get the PyAffy Python package installed under Windows even though it seems to be impossible to create the needed vcvarsal.bat file?

I cannot work with Linux because I am legally blind and there is no good screen reader and magnifier for Linux like the one I use for Windows. Are there different kinds of Pythons, which I could install, to work around this problem? Is there any other packages like PyAffy, which can read in the .cel files of the Affymetrics Yeast2 microarray chip?

Thanks a lot in advance. Thomas. Cell phone: [phone], Email: [e-mail]

Not a direct answer, but you can probably read these Affymetrics's Yeast2 Microarray CEL files with ReadAffy() from the affy package.

did you try affy module in biopython (http://biopython.org/DIST/docs/api/Bio.Affy-module.html)?

No. I was not aware of it. Thanks for having taken the time to share this solution with me. Now I can proceed. Thanks a bunch!

Easy way to install biopython in windows provided on biopython website. copy/pasted from https://pypi.python.org/pypi/biopython/1.70:

Python 2.7.9 onwards, and Python 3.4 onwards, include the package management system “pip” which should allow you to install Biopython with just:

pip install numpy
pip install biopython
