Electronic supplementary material
Electronic supplementary material (animations, movies, audio, large original data, etc.) can add dimension to the article, as certain information cannot be printed or is more convenient in electronic form. Electronic supplementary material will be published in the online version only.
Springer accepts electronic multimedia files (animations, movies, audio, etc.) and other supplementary files to be published online along with an article or a book chapter. This feature can add dimension to the author's article, as certain information cannot be printed or is more convenient in electronic form.
- Supply all supplementary material in standard file formats.
- Please include in each file the following information: article title, journal name, author names; affiliation and e-mail address of the corresponding author.
- To accommodate user downloads, please keep in mind that larger-sized files may require very long download times and that some users may experience other problems during downloading.
Audio, Video and Animations
Your files should meet the following specifications:
- Resolution: 16:9 or 4:3
- Maximum file size: 25 GB
- Minimum video duration: 1 sec
- Supported file formats: avi, wmv, mp4, mov, m2p, mp2, mpg, mpeg, flv, mxf, mts, m4v, 3gp
Text and Presentations
- Submit your material in PDF format; .doc or .ppt files are not suitable for long-term viability.
- A collection of figures may also be combined in a PDF file.
- Spreadsheets should be converted to PDF if no interaction with the data is intended.
- If the readers should be encouraged to make their own calculations, spreadsheets should be submitted as .xls files (MS Excel).
Specialized format such as .pdb (chemical), .wrl (VRML), .nb (Mathematica notebook), and .tex can also be supplied.
Collecting Multiple Files
It is possible to collect multiple files in a .zip or .gz file
- If supplying any supplementary material, the text must make specific mention of the material as a citation, similar to that of figures and tables.
- Refer to the supplementary files as “Online Resource”, e.g., "... as shown in the animation (Online Resource 3)", “... additional data are given in Online Resource 4”.
- Name the files consecutively, e.g. “ESM_3.mpg”, “ESM_4.pdf”.
For each supplementary material, please supply a concise caption describing the content of the file.
Processing of supplementary files
Electronic supplementary material will be published as received from the author without any conversion, editing, or reformatting.
In order to give people of all abilities and disabilities access to the content of your supplementary files, please make sure that
- the manuscript contains a descriptive caption for each supplementary material
- video files do not contain anything that flashes more than three times per second (so that users prone to seizures caused by such effects are not put at risk)
