Suggest correct tutorial content

[Truongphi20]

I'm going through the tutorial and practicing by the Nextflow code. While practicing, I suggested fixing grammar mistakes and suitable commands to run successfully at each step. Steps I have gone through:

PRE-GWAS:

• DATA_FORMATING
• PCA

GWAS:

• ASSOCIATION_TEST
• VISUALIZATION

POST GWAS:

• ANNOTATION
• SNP_HERITABILITY_ESTIMATION <--- Stuck in GCTA-GREML: the X^t * V^-1 * X matrix is not invertible. #7
• LD SCORE REGRESSION
• MAGMA
• FINE MAPPING
• META-ANALYSIS
• PRS
• MEDELIAN RANDOMIZATION
• CONDITIONAL ANALYSIS
• COLOCALIZATION
• TWAS

Hope to contribute a little attempt to an awesome tutorial.

Hi,
thanks a lot for your effort and interest in this tutorial. I would like to merge your code.
Some of the contents for post-GWAS analysis are outdated and the code may not work anymore.
I will try to fix those soon.
