# Readonly profile If you upgrade from EmotivBCI before v3.6.5, you should notice that we change the format of training profiles so that the existing training profile (i.e. created before v3.6.5) will not be fully supported. We call them readonly profiles which can only run at a live mode and cannot run on training mode. These readonly training profiles only support headsets with 14 EEG channels (i.e. EPOC X and Flex with EPOC X config mapping). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://emotiv.gitbook.io/cortex-api/bci/readonly-profile.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
