Loading .mat files
In this exercise, you'll figure out how to
load a MATLAB file using scipy.io.loadmat()
and you'll discover what Python
datatype it yields.
The file 'albeck_gene_expression.mat' is in your working directory. This file contains gene expression data from the Albeck Lab at UC Davis.
This is a part of the course
“Introduction to Importing Data in Python”
Exercise instructions
- Import the package
scipy.io. - Load the file
'albeck_gene_expression.mat'into the variablemat; do so using the functionscipy.io.loadmat(). - Use the function
type()to print the datatype ofmatto the shell.

Introduction to Importing Data in Python
Learn to import data into Python from various sources, such as Excel, SQL, SAS and right from the web.
You've learned how to import flat files, but there are many other file types you will potentially have to work with as a data scientist. In this chapter, you'll learn how to import data into Python from a wide array of important file types. These include pickled files, Excel spreadsheets, SAS and Stata files, HDF5 files, a file type for storing large quantities of numerical data, and MATLAB files.
