3. PDFs
A separate PDF which directly corresponds to the individual XML or SGML data file should be provided for each book review
and/or letter.
If print quality PDFs are available, please submit them. If the journal is not printed, the resolution of the images in the PDF
should be no less than: Line Art 800 dpi, Halftones 300 dpi, Color 600 dpi. All fonts used in the file need to be fully embedded.
Compression for images should be lossless (zip) or highest-quality JPEG. Illustrations should be encoded as vector data with no
erroneous conversion to bitmaps.
4. Supplementary Data
PMC requires all available supplementary material to be submitted in a portable format, such as PDF, .doc, .csv, etc.
Supplementary material should not be externally linked to a www location from the article text as a substitute for submission.
Supplementary material has been defined to include all of the following:
Voluminous material that was used to support the conclusions of the narrative, such as a genomic database or the
multiple data sets for an article that presents the highlights, which can never accompany a paper based on sheer mass.
"Extra" tables that do not display with the work, but that record the measurements on which the article is based, for
example, that need to be available so the peer reviewers can check the article.
Material added to the work for enhancement purposes, such as a quiz, an instructional video, the 3-minute version of
the reaction that was described in the work with narrative and a few still images, a form that can be filled out, etc.
Video
PMC expects good quality video, and will downsample for web streaming if necessary.
If the meaning of the video is not clear due to low quality, it must be improved prior to submission.
Preferred Settings:
Audio codec: AAC
Sample audio bit rate: 128 kbit/s
Video codec: H.264
Video resolution: 480 vertical lines or better
Format: MPEG-4 (mp4) container
Accepted formats: (mov, avi, mpg, mpeg, mp4, mkv, flv, wmv).
Video files larger than 1GB should be split to several episodes, each less then 1GB.
5. Delivery (more details)
PMC requires that data is named and packaged in a compressed archive, such as a zip file, to ensure that the data can be
processed by our automated system. Naming Article Data Files, Naming ZIP File Packages, Revised or Corrected ZIP Files, and
ZIP File Delivery are discussed on this page.
