1. Could somebody else who ha a Windows system maybe try? Just to know if its a general problem or something specific to GenoMax's system.

2. GenoMax, could you try to load "_HTSeq" (with the underscore) directly, as follows?

C:\>cd \Python27\Lib\site-packages\HTSeq

C:\Python27\Lib\site-packages\HTSeq>c:\Python27\python.exe
Python 2.7.4 (default, Apr  6 2013, 19:54:46) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import _HTSeq

[Simon Anders]

Interesting. Just ran "dependency walker" on my system, and I don't have IESHIMS.DLL either, although everything is working for me. Also, it's a "delayed dependency", so it wouldn't cause an issue right at loading.

[GenoMax]

When I checked _HTseq.pyd with "dependency walker" it is complaining that "IESHIMS.DLL" can't be found. I will try to see if I can diagnose this further.

[GenoMax]

Here it is. Looks the same at first glance to me.

Could you post a list of all file in C:\Python27\lib\site-packages\HTSeq\, please? With file extensions, if possible. Or, maybe compare with my system, where the directory looks like this:

C:\Python27\Lib\site-packages\HTSeq>dir
 Volume in drive C has no label.
 Volume Serial Number is BC62-98E8

Lot of people want to use this package on windows so "fighting windows" on your part is worthwhile

We are not in the clear yet. This is the latest result.

Okay, after an hour of fighting with Windows (even the easiest things are hard on an OS that one uses less than once a year), I found the mistake and fixed it.

Please try HTSeq-0.5.4p2.win32-py2.7.exe and let me know if it still fails.

[GenoMax]

Seems that "_StepVector.dll" is really missing in this binary package. I'll try to fix it.

Thanks Simon.

If you can post an update to this thread when you have a chance to fix that it would be great.

It's hard to say what's wrong if you don't post complete session logs (i.e., all commands typed plus all output and error messages)

Simon,

On a windows 7 (64-bit) machine: I installed 32-bit python, NumPy (BTW: the www.scipy.org link you have in the instructions does not work any more, I downloaded NumPy from: https://pypi.python.org/pypi/numpy).

Trying "import HTSeq" as recommended in your instructions is generating the following error. Googling around seems to indicate that a VS2010 DLL may be missing but I would like to get your take on what is going on.

[mlkerber]

I'm having the same issue with HTSeq on my PC. Made sure I was using Python 2.7, reinstalled numpy, reinstalled HTSeq, also without success.

Is there an alternative for getting read counts from SAM file produced by BWA?

[kakseq]

hi,

Thanks for your help. For now I guess I'll run HTSeq on a mac instead and look into seqtk for future use.

[kmcarr]

An alternative to HTSeq for randomly sampling a FASTQ file is Heng Li's seqtk. It can subsample a specific number of reads from a file or a fraction of the input as with Simon's HTSeq script.

[GenoMax]

I have sent some email to Simon Anders (not sure if he is on this forum). It appears that the current version of HTseq for windows is not working (for me either).
