'Bowtie2 Envronmental Variables

I am completely lost with bowtie2 environment variables. I am using a mac and I downloaded the source file of bowtie2-2.2.5 and performed "make"

The absolute path where this folder is found is 

/Users/Lab/Documents/CLI_Programs/bowtie2-2.2.5/

I want to be able to run the command bowtie2 without having to be in the folder that contains this. I tried changing my .bash_profile with 

export BT2_HOME=/Users/Kumka/Documents/CLI_Programs/bowtie2-2.2.5/

I don't know what this is supposed to look like... Also when I run ./bowtie2 within the folder the final line is 

(ERR): bowtie2-align exited with value 1

Is it even compiled correctly?

Solution 1:[1]

open ~/.bashrc

Add the following path into the .bashrc and save

PATH=$PATH:/Users/lab/Documents/CLI_Programs/bowtie2-2.2.5

Why don't they just make it so explicit with an example... Geez

Solution 2:[2]

I have the same output here

(ERR): bowtie2-align exited with value 1

This output is caused by insufficient memory

Out of memory allocating the ebwt[] array for the Bowtie index.  
Please try again on a computer with more memory.
