    Hello amitbik,

    Looks like we resolved your problem over email. The next release of khmer included expanded installation instructions. They can be previewed at http://khmer.readthedocs.org/en/late...r/install.html

    Cheers,

    Error in using normalize-by-median.py

    Hi, crusoe

    An error is coming while using normalize-by-median.py.

    python normalize-by-median.py -h

    Traceback (most recent call last):
    File "normalize-by-median.py", line 19, in <module>
    import screed
    ImportError: No module named screed

    If i am running any command also i am getting the same error. Is there any problem with python?

    Please help me..

    Thanks in advance..

    I know that this is an old thread but as the lead developer on khmer I wanted to clear a few things up.

    Firstly, thanks for using our software!

    We've revamped the installation process considerably in the last year. I agree, assuming root access is not a good idea.



    I am very happy to help with any other khmer related issues. Alas I haven't found a way to receive an alert whenever someone mentions khmer on seqanswers. In the mean time please feel free to alert us via GitHub about any issues:

    In-memory nucleotide sequence k-mer counting, filtering, graph traversal and more - Issues · dib-lab/khmer


    Or you can email us: [email protected]

    Cheers,

    Thank you lorendarith. It seems to be working now. I wonder why the installation guide assumes you will have root access.

    Yeah, the tutorial does not take some things into account...

    Anyway, since you do not have root permissions I do believe you have the PYTHONPATH variable with the location of the folder where you install your python libraries already exported. If you've already installed screed successfully, all you need to do is append the khmer path to the PYTHONPATH variable

    So you should have something like:
    export PYTHONPATH=/whatever/path/to/the/library/folder/

    Add:
    export PYTHONPATH=/whatever/path/to/the/library/folder/:/path/to/khmer/python/

    Note that "khmer/python" is in the folder which you cloned from github after the make test command. After you changed the bashrc or bash_profile, start a new terminal and try running the "/khmer/scripts/normalize-by-median.py" script and it should work.

    Hope this helps...

    Diginorm Installation

    Hello,

    Does anyone have experience with installing Diginorm in a linux server without root access? The installation guide assumes you are using Amazon EC2 and have root access:


    I tried installing on a virtual box ubuntu machine where I had root access and I still ran into issues. When I ran ~/khmer/scripts/normalize-by-median.py it said that the khmer module could not be found. But running make for khmer didn't help. Seems like other people may have had issues installing as well:

    Recent Advances in Sequencing Analysis Tools
    by seqadmin


    The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
