Hello, I have installed python 3.9.1 and indeed this is confirmed in the terminal when looking to the version. However when launching Biopython I get the message "Biopython requires Python 3.6 or later. Python 2.7 detected." How is this possible? What to do? Thanks.

Python is generally symlinked to python v.2.x. Can you explicitly try `python3`? -
New python versions usually break a lot of modules, especially low-level ones like pyinstaller and cffi. I usually wait for a revision or two before upgrading to let module maintainers catch up. Waiting also lets the PSF fix any bugs and security holes that are bound to be lurking somewhere.Last edited by AlexPhilip; 12-09-2021, 07:10 AM.2025Comment

The old version is better!Comment

I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.
Here are nine questions we think about, in roughly the order they matter, before...06-18-2026, 07:11 AM -
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.
