1. Concepts and ideas

1.1. Replicate your results by different people

1.1.1. Cannot be replicated due to:

1.1.1.1. No time

1.1.1.2. No money

1.1.1.3. Unique

1.1.2. Make code available to everyone

1.2. Validation of data analysis

1.3. Research pipeline

1.3.1. Article

2. Scripting your analysis

2.1. Script everything

3. Structure of data analysis

3.1. Steps

3.1.1. Define a question

3.1.1.1. Narrow as much as possible

3.1.1.2. This helps remove the noise of other data

3.1.2. Define ideal data set

3.1.2.1. May depend on your goal

3.1.2.1.6. Mechanistic

3.1.3. What data you can access

3.1.3.1. Free on the web

3.1.3.2. Buy data

3.1.3.3. Might need to generate it

3.1.4. Obtain data

3.1.4.1. Try to get raw data

3.1.4.2. If got from web: record url and time accessed

3.1.5. Clean data

3.1.5.1. if it preprocessed already, understand how

3.1.5.2. understand souce of data

3.1.5.3. determine if data is good enough

3.1.5.3.1. quit

3.1.5.3.2. change data
