Manuscripts must be written in concise English. For help on scientific writing, or preparing your manuscript in English, please see Springer's Author Academy.
The text should be written double-spaced and justified in single column format using 12-point font size and Times New Roman font typeface. The manuscript must be prepared using A4 or Letter typeset with approximately 25 mm (1 in.) margins at all sides. The manuscript should not contain any headers or footers.
Include line and page numbering
Units of Measurement: Authors are encouraged to use the International System of Units (SI units). Other units may be given in parenthesis as supplement; however, the presentation format should be consistent throughout the manuscript.
Do not use page breaks in your manuscript
The following word processor file formats are acceptable for the main manuscript document:
Microsoft word (DOC, DOCX)
Rich text format (RTF)
TeX/LaTeX (use either Springer's or BioMed Central's TeX template)
Please note: editable files are required for processing in production. If your manuscript contains any non-editable files (such as PDFs) you will be required to re-submit an editable file if your manuscript is accepted.
Note that figures must be submitted as separate image files, not as part of the submitted manuscript file. For more information, see 'Preparing figures' below.
Additional information for TeX/LaTeX users
Please use either BioMed Central's or Springer's TeX template and BibTeX stylefile if you use TeX format. Submit your references using either a bib or bbl file. When submitting TeX submissions, please submit both your TeX file and your bib/bbl file as manuscript files. Please also convert your TeX file into a PDF (please do not use a DIV file) and submit this PDF as a supplementary file with the name 'Reference PDF'. This PDF will be used by our production team as a reference point to check the layout of the article as the author intended. Please also note that all figures must be coded at the end of the TeX file and not inline.
The Editorial Manager system checks for any errors in the Tex files. If an error is present then the system PDF will display LaTex code and highlight and explain the error in a section beginning with an exclamation mark (!).
All relevant editable source files must be uploaded during the submission process. Failing to submit these source files will cause unnecessary delays in the production process.
BioMedCentral_article (ZIP format) - preferred template
Springer article svjour3 (ZIP format) - preferred template
birkjour (Birkhäuser, ZIP format)
article (part of the standard TeX distribution)
amsart (part of the standard TeX distribution)
There is no limit on the manuscript length for research articles and review articles, but no more than 8 manuscript pages, including tables and illustrations, are preferred for short communications and discussions.
Use Arabic numerals in appropriate sequence for each heading and subheading in the body of the manuscript. For next lower level subheading, do not use numbering, as shown. Each heading should be aligned center, and all other subheadings and lower level subheadings should be aligned left.
• For next lower level subheading 1
- For next lower level subheading 2

Data and materials
For all journals, SpringerOpen strongly encourages all datasets on which the conclusions of the manuscript rely to be either deposited in publicly available repositories (where available and appropriate) or presented in the main paper or additional supporting files, in machine-readable format (such as spread sheets rather than PDFs) whenever possible. Please see the list of recommended repositories in our editorial policies.
For some journals, deposition of the data on which the conclusions of the manuscript rely is an absolute requirement. Please check the Instructions for Authors for the relevant journal and article type for journal specific policies.
For all manuscripts, information about data availability should be detailed in an ‘Availability of data and materials’ section. For more information on the content of this section, please see the Declarations section of the relevant journal’s Instruction for Authors. For more information on SpringerOpen's policies on data availability, please see our editorial policies.
Formatting the 'Availability of data and materials' section of your manuscript
The following format for the 'Availability of data and materials section of your manuscript should be used:
"The dataset(s) supporting the conclusions of this article is(are) available in the [repository name] repository, [unique persistent identifier and hyperlink to dataset(s) in http:// format]."
The following format is required when data are included as additional files:
"The dataset(s) supporting the conclusions of this article is(are) included within the article (and its additional file(s))."
For databases, this section should state the web/ftp address at which the database is available and any restrictions to its use by non-academics.
For software, this section should include:
Project name: e.g. My bioinformatics project
Project home page: e.g. http://sourceforge.net/projects/mged
Archived version: DOI or unique identifier of archived software or code in repository (e.g. enodo)
Operating system(s): e.g. Platform independent
Programming language: e.g. Java
Other requirements: e.g. Java 1.3.1 or higher, Tomcat 4.0 or higher
License: e.g. GNU GPL, FreeBSD etc.
Any restrictions to use by non-academics: e.g. licence needed
Information on available repositories for other types of scientific data, including clinical data, can be found in our editorial policies.
See our editorial policies for author guidance on good citation practice.
What should be cited?
Only articles, clinical trial registration records and abstracts that have been published or are in press, or are available through public e-print/preprint servers, may be cited.
Unpublished abstracts, unpublished data and personal communications should not be included in the reference list, but may be included in the text and referred to as "unpublished observations" or "personal communications" giving the names of the involved researchers. Obtaining permission to quote personal communications and unpublished data from the cited colleagues is the responsibility of the author. Footnotes are not allowed, but endnotes are permitted. Journal abbreviations follow Index Medicus/MEDLINE.
Any in press articles cited within the references and necessary for the reviewers' assessment of the manuscript should be made available if requested by the editorial office.
Equations are numbered sequentially and should take up individual lines. Every symbol must be defined. Letters and numerals must be distinguished clearly. You may use the solidus or slash (“/”) for single-level expressions, e.g., 1/(a + b), that can fit in a single line, but not for stacked equations within the text.
Number all tables and figures in the order that they appear in the text. Place the table number and title line at the top center of the table. Place the figure number and title at the bottom center of the figure. Leave one line space after the table and after the figure title. Use letters (a), (b), (c), etc., to label figure parts and their respective subcaptions, if applicable. (Sub-captions also may be integrated into the main caption; see the examples.) If the figure has sub-parts, place the sub-titles in the title of figure and descriptions in a caption. If necessary, indicate the unit of contents using brackets (; see the examples).
Table 1. Title of table (above the table) should follow after table number, and one space ((a) title of first sub-part, (b) title of second sub-part, (c) title of third sub-part) [unit: mm]
Figure 1. Title of figure or photograph (below the figure) should follow after figure number, and one space
When preparing figures, please follow the formatting instructions below.
Figures should be provided as separate files, not embedded in the main manuscript file.
Figure titles (max 15 words) and legends (max 300 words) should be provided in the main manuscript, not in the graphic file.
Each figure of a manuscript should be submitted as a single file that fits on a single page in portrait format.
Tables should NOT be submitted as figures but should be included in the main manuscript file.
Multi-panel figures (those with parts a, b, c, d etc.) should be submitted as a single composite file that contains all parts of the figure.
Figures should be uploaded in the correct orientation.
Figure keys should be incorporated into the graphic, not into the legend of the figure.
Each figure should be closely cropped to minimize the amount of white space surrounding the illustration. Cropping figures improves accuracy when placing the figure in combination with other elements when the accepted manuscript is prepared for publication on our site. For more information on individual figure file formats, see our detailed instructions.
Individual figure files should not exceed 10 MB. If a suitable format is chosen, this file size is adequate for extremely high quality figures.
Please note that it is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce figures (or tables) that have previously been published elsewhere. In order for all figures to be open access, authors must have permission from the rights holder if they wish to include images that have been published elsewhere in non open access journals. Permission should be indicated in the figure legend, and the original source included in the reference list.
Figure file types
We accept the following file formats for figures:
EPS (suitable for diagrams and/or images)
PDF (suitable for diagrams and/or images)
Microsoft Word (suitable for diagrams and/or images, figures must be a single page)
PowerPoint (suitable for diagrams and/or images, figures must be a single page)
TIFF (suitable for images)
JPEG (suitable for photographic images, less suitable for graphical images)
PNG (suitable for images)
BMP (suitable for images)
CDX (ChemDraw - suitable for molecular structures)
Figure size and resolution
Figures are resized during publication of the final full text and PDF versions to conform to the SpringerOpen standard dimensions, which are detailed below.
Figures on the web:
width of 600 pixels (standard), 1200 pixels (high resolution).
Figures in the final PDF version:
width of 85 mm for half page width figure
width of 170 mm for full page width figure
maximum height of 225 mm for figure and legend
image resolution of approximately 300 dpi (dots per inch) at the final size
Figures should be designed such that all information, including text, is legible at these dimensions. All lines should be wider than 0.25 pt when constrained to standard figure widths. All fonts must be embedded.
Figure file compression
Vector figures should if possible be submitted as PDF files, which are usually more compact than EPS files.
TIFF files should be saved with LZW compression, which is lossless (decreases file size without decreasing quality) in order to minimize upload time.
JPEG files should be saved at maximum quality.
Conversion of images between file types (especially lossy formats such as JPEG) should be kept to a minimum to avoid degradation of quality.
If you have any questions or are experiencing a problem with figures, please contact the customer service team at firstname.lastname@example.org.
When preparing tables, please follow the formatting instructions below.
Tables less than one A4 or Letter page in length can be placed in the appropriate location within the manuscript.
Tables larger than one A4 or Letter page in length can be placed at the end of the document text file. Please cite and indicate where the table should appear at the relevant location in the text file so that the table can be added in the correct place during production.
Larger datasets, or tables too wide for A4 or Letter landscape page can be uploaded as additional files. Please see [below] for more information.
Tabular data provided as additional files can be uploaded as an Excel spreadsheet (.xls ) or comma separated values (.csv). Please use the standard file extensions.
Tables should not be embedded as figures or spreadsheet files, but should be formatted using ‘Table object’ function in your word processing program.
Color and shading may not be used. Parts of the table can be highlighted using superscript, numbering, lettering, symbols or bold text, the meaning of which should be explained in a table legend.
Commas should not be used to indicate numerical values.
If you have any questions or are experiencing a problem with tables, please contact the customer service team at email@example.com.
Preparing additional files
As the length and quantity of data is not restricted for many article types, authors can provide datasets, tables, movies, or other information as additional files.
All Additional files will be published along with the accepted article. Do not include files such as patient consent forms, certificates of language editing, or revised versions of the main manuscript document with tracked changes. Such files, if requested, should be sent by email to the journal’s editorial email address, quoting the manuscript reference number.
Results that would otherwise be indicated as "data not shown" should be included as additional files. Since many web links and URLs rapidly become broken, SpringerOpen requires that supporting data are included as additional files, or deposited in a recognized repository. Please do not link to data on a personal/departmental website. Do not include any individual participant details. The maximum file size for additional files is 20 MB each, and files will be virus-scanned on submission. Each additional file should be cited in sequence within the main body of text.
