Open source software for scientists - our top five recommendations

As part of our drive to help reduce barriers to scientific publishing, today we would like to share Nextgenediting’s top five open source or free alternatives to commercial scientific software packages. Although the vast majority of the submissions we receive are written in Microsoft Word with citations embedded using Endnote, we also use the freely available programs listed below to help edit and prepare papers for submission. This has become even more important as we liaise with scientists from low- and middle-income countries as part of the Global Initiative, who sometimes cannot afford the (sometimes extremely) high cost of commercial software. Please let us know if you have any other recommendations or questions about the use of these packages.

1. Image processing and manipulation - GIMP (The GNU Image Manipulation Program)

GIMP is a fantastic and versatile alternative to Adobe Photoshop, feely downloadable for all platforms (Mac, Windows, Linux, and others). We find it particularly useful for image conversion in preparation for manuscript submission, especially for producing the high-resolution 300 dpi figures frequently required by the journals. Although the learning curve is relatively steep, there is comprehensive online documentation (including in multiple languages) that holds your hand through basic tasks, such as image re-sizing, cropping, and how to add text to figures. Although CMKY is not supported, we use the Separate+ plugin when conversion is necessary. Give it a try!

2. Statistical analysis - PSPP

Although SPSS is probably the dominant statistical analysis software package used in the social and life sciences, its high cost and annual license fees make it inaccessible to many researchers and students, particularly those already working in under-resourced environments. Although R is a phenomenally powerful (and free) statistical programming environment, it can be difficult to learn due to the lack of an intuitive graphical interface and need to grasp a new programming language (great in theory, just not going to happen in practice for most of us). PSPP is an open source alternative to SPSS that is certainly worth a shot. It is limited to basic analyses - descriptive statistics, linear regression, t-tests, and the like - but those familiar with the SPSS interface will have no problems using it since it is almost identical. If more people start to use it, perhaps we will see development of more complex functions.

3. Citation management - Bibus

Learning how to use citation management/bibliographic software is a must for academics. The proprietary software packages are not usually prohibitively expensive, but it would be wise to check with your institution first to see whether they have cheaper institutional licensing arrangements and training courses available. However, what about a free alternative? We recommend Bibus, a powerful reference management software package that integrates with MS Word and OpenOffice and allows online searching of PubMed via an intuitive user interface. One drawback though - while you can get Bibus to work on a Mac, it does not currently integrate with Word for Mac.

4. Typesetting and word processing - LaTeX

The scientific community is, without doubt, tied down to MS Word for document preparation and that is unlikely to change in the near future. The transition to any other word processing program can seem daunting, and most of us who have tried have generally failed. OpenOffice.org is a free alternative to MS Office and, as explained above, can be used with citation management software to good effect. However, LaTeX, another powerful ‘programming language’, might be worth exploring if you are embarking on a large document that requires a professional finish, such as a thesis. LaTeX produces documents with superior typesetting and is particularly useful if the document contains a lot of maths. It is free and easily extensible (see the Comprenhesive TeX Archive Network, CTAN). It does take some getting used to because it is not WYSIWYG, but consider it if you are about to undertake a ‘long-haul’ project. See also the great resource from the Department of Engineering at the University of Cambridge to help you get started with LaTeX.

5. Open Access (OA) article searching - CORE Research Mobile App (for iOS and Android)

Sometimes finding the data can be as difficult as processing it, especially when a lot of papers are still hidden behind paywalls. We recently found this nifty app from the UK’s Open University, which allows you to search and download freely available, full-text articles and read them on your device (in another app of your choosing, such as Kindle). The repository currently contains over 18 million open access articles. A great place to look if you need to find full text to support your research and don’t have access to journal subscriptions.

So there we are - our top five open source software packages for scientists - but please suggest your own too using the comments box below.
