    Error in Biopython

    Newbie to Biopyton here....

    I'm getting the following error, from: can't read /var/mail/Bio.Seq, when I run the following at the terminal: from Bio.Seq import Seq

    I'm new to programming and VERY new to Biopython, so any help is greatly appreciated.

    Thanks in advance!

    Make sure you're at the python prompt, >>> from Bio.Seq import Seq

    For all the Scientists turned Computational Biologists that asked questions obvious to CS folks.

      To expand on Kimist99's answer, you shouldn't run Python commands directly at the Unix terminal, e.g.

      Code:
      $ from Bio.Seq import Seq
      from: can't read /var/mail/Bio.Seq
      Here "$" is shorthand for the Unix terminal prompt, which usually ends with a dollar sign.

      This asked Unix to run the tool "from", which is command line tool for working with emails. You need to run Python first, and inside Python try the import line:

      Code:
      $ python
      Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
      [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
      Type "help", "copyright", "credits" or "license" for more information.
      >>>
      That ">>>" is the Python prompt, where you could type a Python statement. e.g.

      Code:
      $ python
      Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
      [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
      Type "help", "copyright", "credits" or "license" for more information.
      >>> from Bio.Seq import Seq
      >>> quit()
      You would typically create a text file whose name ends with ".py" containing your python script, e.g. "example.py", and run that at the Unix terminal with:

      Code:
      $ python example.py

        Agree with all of the above and highly recommend Anaconda. It is a completely free Python distribution (including for commercial use and redistribution). It includes over 195 of the most popular Python packages for science, math, engineering, data analysis. http://continuum.io/downloads

        Spend five minutes to get used to IPython and the notebook and your life will be so much easier!

            From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
            by SEQadmin2


            Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


            The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

            Single-Cell Sequencing at an Inflection Point: Early Impacts of New Platforms and Emerging Trends
            by SEQadmin2


            With the launch of new single-cell sequencing platforms in 2026, the field stands at an exciting inflection point. This article surveys the most impactful advances in the field and discusses how they’re reshaping research in cancer, immunology, and beyond.


            Introduction

            Single-cell sequencing technologies have undergone remarkable advances over the past decade, transitioning from low-throughput experimental approaches to highly scalable platforms capable of...

            Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
            by SEQadmin2

            Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


            Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
