The GLIMMPSE web services layer consists of several web services which perform power calculations and support basic file operations. The web services are implemented as Java Servlets. The modules are designed to be run in an application server such as Apache Tomcat. The web services layer contains the following applications.
The power service calculates power and sample size for the general linear multivariate model. It receives study design information from the user interface and produces a list of power or sample size results.
The file service is used to save and upload study design information in GLIMMPSE.
