Studyset
Overview
A studyset is a collection of studies and serves as the primary input to a meta-analysis.
Functions
If an existing studyset is close to what you want or provides a good starting point, you may clone the studyset. From there you can add additional studies or remove studies from the studyset. If you would like to change which analyses are included for analysis in the studyset, we recommend you use annotations instead.
Annotation
Overview
Annotations serve three functions:
- human-readable documentation (for example, following PRISMA)
- Specifying co-variates to be used in the meta-analysis
- Filtering Analyses for inclusion in the meta-analysis
Annotations can be thought of like an excel sheet, where the columns are variables serving one of the three functions mentioned above, and the rows are each analysis and its value for that variable. For example, let's say we were to create an annotation for purpose (3). To filter analyses for inclusion, we can create an "include" column may have a corresponding values of "True" or "False" for each analysis indicating whether to include the analysis in the meta-analysis.
Functions
Annotations can also be cloned if you disagree with an existing annotation you do not own and want to edit it.
Study
Overview
A study is a publishable unit of research containing neuroimaging data. The data can be represented as peak coordinates or actual images. The study is connected to the original journal it was published in.
Functions
Studies can be created, cloned, and edited to accomodate your needs for your meta-analysis
Analysis
Overview
An analysis represents a single statistical contrast between any number of groups/conditions. The contents of an analysis include the terms applied to the groups/conditions and their respective weights in the contrast. An analysis also contains the results of the statistical contrast either with an image and/or a table indicating significant results
Condition
Overview
A condition is term/word that represents a psychological (e.g., 2-back), physical (e.g., biking)
