Tutorial
+ ++ In this short tutorial a set of 1141475 HIV integration sites are analysed using Enhort. + +
+Upload integration sites
++ +
+ At first, integration sites have to uploaded in a .bed-file. In this example set of about 1m HIV integration + sites taken from the + Retrovirus Integration Database is used. The wizard is selected on + the main page: + +
+
+ And on the following page the .bed-file is selected on the local computer. + +
+Select annotations
++ + + The sites are then uploaded and the overview for available annotations is shown: + +

+ Single annotations can be selected by clicking on the blue squares. A set of annotations for a cell line or + all annotations in a column + can be selected by clicking on the row or column header. For example, all cell line independent annotations + are selected in the following example, as well as + annotations for HeLa: + +
+
Review results and add a covariate
++ +
+ The results for the given sites and selected covariates are then displayed in a table, containing the effect + size and p value of each annotation, as well + as overview over the annotation groups. Each row can be expanded to get exact integration counts for each + annotation: + +
+
+ + From here the user can select covariates to alter the integation preference + of the background control sites. For example, HIV is known to integrate near genes which is observable in + the upper image. The annotation track RefSeq genes can + be selected as covariate to adapt the background for this known preference. To do this the marked checkbox + is selected and with the button 'Run again' the + background is changed. In the following image we see RefSeq genes was added to list of covariate on the + right and now has the exact same integration preference as the HIV sites: + +
+
+ + This adaptation then changes the significance and fold change of several annotations tracks in the main + table. In the following the complete table of selected annotations is shown + with 'houskeeping genes' expanded to show exact integration counts: +
+ +
Further possibilites
++ +
+ In the upper part different tabs are located containing further analysis of the given sites, as well as the + option to download the background sites or results. + Depending on the individual scientific question other covariates can be selected to build a specialized + background model. +
