Preparing additional files

Although KSSTA does not restrict the length and quantity of data included in an article, we encourage authors to provide datasets, tables, movies, or other information as additional files.

Please note: All additional files will be published along with the 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 should be sent by email to kssta@esska.org, quoting the Manuscript ID number.

Results that would otherwise be indicated as “data not shown” can and should be included as additional files. Since many weblinks and URLs rapidly become broken, KSSTA requires that supporting data are included as additional files, or deposited in a recognised repository. Please do not link to data on a personal/departmental website. The maximum file size for additional files is 20 MB each, and files will be virus-scanned on submission.

Additional files can be in any format, and will be downloadable from the final published article as supplied by the author. We recommend CSV rather than PDF for tabular data.

Certain supported files formats are recognised and can be displayed to the user in the browser. These include most movie formats (for users with the Quicktime plugin), mini-websites prepared according to our guidelines, chemical structure files (MOL, PDB), geographic data files (KML).

If additional material is provided, please list the following information in a separate section of the manuscript text:

  • File name (e.g. Additional file 1)
  • File format including the correct file extension for example .pdf, .xls, .txt, .pptx (including name and a URL of an appropriate viewer if format is unusual)
  • Title of data
  • Description of data

Additional files should be named “Additional file 1” and so on and should be referenced explicitly by file name within the body of the article, e.g.

Additional file formats

Ideally, file formats for additional files should not be platform-specific, and should be viewable using free or widely available tools. The following are examples of suitable formats.

  • Additional documentation
    • PDF (Adode Acrobat)
  • Animations
    • SWF (Shockwave Flash)
  • Movies
    • MP4 (MPEG 4)
    • MOV (Quicktime)
  • Tabular data
  • XLS, XLSX (Excel Spreadsheet)
  • CSV (Comma separated values)

As with figure files, files should be given the standard file extensions.
