====== Worked example Prediction - Train ======

**1.** Log in into HiPathia. For further information on this step visit [[logging_in|Logging in]].

**2.** We will work with a Breast Cancer dataset from the repository The Cancer Genome Atlas. You can download the expression matrix and the experimental design from these links:

  * Expression matrix: {{:brca_genes_vals_bn.txt|}}
  * Experimental design: {{:brca_normal-basal_ed.txt|}}

**3.** Upload the data to HiPathia in the data panel by clicking on //My data//. For further information on this step visit [[upload_your_data|Upload your data]].

**4.** Press the //Prediction// button.

**5.** In the //Type// panel select //Train new predictor//.

**6.** In the //Input data panel// select //Expression matrix//. Press the //File browser// of the //Expression matrix file//, and select the desired file.

**8.** Select Human as species (by default).


**9.** In the //Pathways// panel select all the pathways (by default).

**10.** In the //Job information// panel, press the //File browser// button and select the desired output folder. In this case we will use //analysis_BRCA//. Give a name to the job, for example "BRCA train model".
