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:

• [x] DATA_FORMATING
• [x] PCA

GWAS:

• [x] ASSOCIATION_TEST
• [x] VISUALIZATION

POST GWAS:

• [x] ANNOTATION
• [ ] SNP_HERITABILITY_ESTIMATION <--- Stuck in #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 Some of the contents for post-GWAS analysis are outdated and the code may not work anymore.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.
