# Family tree legend
While adding a new case, you will build a pedigree and annotate each of the samples with data required for analysis.
After the case has been created, the family tree is available in the [Case details](/emedgene/emedgene-analyze-manual/getting_around_the_platform/cases_tab/case_details.md) panel (righthand panel of the Cases page).
## Family tree legend:
1. **Icon fill color** in other pedigree members indicates the presence or absence of the proband's phenotypes in a present sample (regardless of the potential presence of additional unrelated phenotypes).
{% columns %}
{% column width="41.66666666666667%" valign="middle" %}
{% endcolumn %}
{% column width="58.33333333333333%" %}
1. **Filled:** The individual is affected by all of the proband's phenotypes.
2. **Half-filled:** The individual is affected by some of the proband's phenotypes.
3. **Empty:** The individual is not affected by any of the proband's phenotypes.
{% endcolumn %}
{% endcolumns %}
2\. **Icon color intensity** denotes whether sample files have been uploaded for the particular individual.
{% columns %}
{% column width="41.66666666666667%" valign="middle" %}
{% endcolumn %}
{% column width="58.33333333333333%" %}
1. **Full color:** The sample has files loaded in the case.
2. **Faded color:** No sample files are available.
{% endcolumn %}
{% endcolumns %}
3\. **Icon line type** indicates whether the sample is considered or excluded during analysis (relevant to samples with uploaded files only)
{% columns %}
{% column width="41.66666666666667%" valign="middle" %}
{% endcolumn %}
{% column width="58.33333333333333%" %}
1. **Solid:** The sample is included in the analysis.
2. **Dashed:** The sample is ignored by Inheritance filters and the AI Shortlist algorithm, but you still can explore its genotypes.
{% endcolumn %}
{% endcolumns %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.bioinsight.illumina.com/emedgene/emedgene-analyze-manual/launching-analysis/creating_a_single_case/2.-family-tree/family_tree_legend.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
