I want to submit my article in a reputed SCI journal. Is it necessary to read and cite articles from sci journals only so as to publish your article in some other SCI journal ?
I am asking this because there are a lot of non-SCI journals as well (including the predatory and just-for-profit fake journals) and if we cite some data particularly from those fake journal articles, will it not somehow make our article of poor quality and hinder the chances of getting my article selected in some SCI journals ?

Edit:
SCI= Science Citation Index

I have extensively researched about a new area as part of my Doctoral research and want to write and publish a review article in some Science Citation Indexed (SCI) journal. But the problem is that there are only about 20 articles published till date on this new area. I have seen many review papers on other areas published in SCI journals and found that normally the number of cited and referenced articles are quite high (sometimes even above 300 papers). And then there are non-SCI journals where review papers are having very less number of cited and referenced articles (20-50 or more).

I have two questions regarding writing of survey papers

Firstly, if one of the technical papers reviewed has a number of figures. Take for example: Figure 4 is “Data model” and Figure 8 is “Mechanism structure”. In the survey paper is it enough modification (for a waver of official permission) to merge these two into one figure and cite. Say, Figure X: Data model and Mechanism Structure adapted from [ref]?

Secondly, in the case when author A proposes “Data model” and “mechanism structure” in paper [30] and [35] i.e four entirely different diagrams. Is it sufficient as modification (for a waver for official permission) if in a survey, all four combined in one figure.

Thanks in advance

For an accepted paper about to be produced (not open access), the author should agree to terms that all illustrations, tables etc. have recieved permissions from the copyright owner. If the author agrees, the paper takes the copyright of the Journal. The question is that, for an inexperienced author, could the journal take up the responsibility (e.g through an office) to take care of issues of permissions etc. before beginning the production process? Thus, they would look into: which figures, tables etc. require permission and they would go through the process. For instance using a Rightslink account etc.

Edit: If not, could they (at least some of them) offer advice on what and what may require permissions from an accepted manuscript?

1.) In case the the original paper has a number of figures. Take for example: Figure 4 is “Data model” and Figure 8 is “Mechanism structure”. If I write my paper, and merge these two into one figure. Is it sufficient to cite it as (my review paper) Figure X: Data model and Mechanism Structure adapted from [44]? Is this modification enough as a waver for permission (and its payment)?

2.) What of the case when author A proposes “Data model” and “mechanism structure” in paper [30] and [35]. Is it sufficient if in my own paper, I have all four combined in one figure. Say, Figure Z: Data Model and Mechanism Structure proposed by author X adapted from [30,35]? Does this require permission also.
