SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Matrix Biology publishes Regular Research Papers, Brief Reports, Commentaries, Mini Reviews, Full Length Reviews and Announcements.
Regular Research Papers are studies utilizing most scientific technologies including molecular biology, cell biology, immunochemistry, structural biology, computational biology, theoretical biology, and macromolecular chemistry where the subject is extracellular matrix or is substantially related to matrix and its biological role. The journal will publish articles that are scientifically rigorous, complete within a logical framework, and, most importantly, address molecular or cellular mechanisms that are timely and represent above average significance.
Brief Reports are short papers that meet the same standards of quality and field of interest as regular papers, but have a narrower scope and a more focused interest. Brief reports should present new information of exceptional novelty, importance and interest to the broad readership of the journal. Reports should have a maximum of 3 figures, and no longer than 30,000 characters, including spaces. There are no limitations for references.
Commentaries are brief reviews that present a sharply focused view of a rapidly advancing area of research. Authorship is normally by invitation. Generally, commentaries include a manuscript of 6-10 double-spaced pages with 1-2 schematics. References are limited to 20-30.
Mini Reviews are timely and original analyses of current topics of high interest. The mini-reviews should summarize the general concepts in the field, provide a brief summary of the new information and define unresolved questions about currently available data. The minireviews must contain up to 3 original graphics of high quality or equivalent images, and a manuscript containing 12-15 double-spaced pages. There are no limitations for references. We do not accept previously-published graphics or images. The Editor-in-Chief should be consulted in advance by anyone wishing to submit an unsolicited minireview.
Full Length Reviews are comprehensive and critical analyses of topics that have been under investigation for some time. Most of them are invited reviews from experts in the relevant topic. The reviews must contain up to five high-quality, original graphics or equivalent images, and a manuscript containing 20-40 double-spaced pages. No limitations for references. We do not accept previously-published graphics or images. The Editor-in-Chief should be consulted in advance by anyone wishing to submit an unsolicited full-length review.
Announcements of national or international meetings may be published in Matrix Biology.
