Pipeline for creating a SNP dataset from scratch

Hello, I am a real bioinformatic noob. I have to start a project to make an SNP dataset from scratch. I have ~100 NGS sequencing datasets and a reference genome. My end goal is to create an SNP dataset for conducting genome-wide association mapping.

Can someone please give me a link or reference or tutorial showing a step by step procedure for making an SNP dataset from raw NGS sequence data?

I know it is hard to find a perfect tutorial as there are many. But any suggestions will be much appreciated. I really have no experience in this field and do not know from where to start. Thank you.

I have to start a project to make an SNP dataset from scratch

Based on what you wrote below this is not where you want to start. Creating a SNP dataset from scratch will be a difficult task even for someone who has been doing informatics for a while. Here is one example of a tutorial that walks you though basics.

This is a set of video tutorials that looks comprehensive.

Thank you very much for those two informative links. Yes, I can feel the difficulty level already.

Depending upon organism the variant calling method will differ, it will be easy to suggest tutorials and publications if you mention the organism name.

It is an haploid microorganism (Plant fungi)

Thrown straight into the deep end?- no support from your supervisor?

You should take a look through the documentation for the Genome Analysis ToolKit (GATK). Unfortunately, nobody here has the time to take you through this step-by-step over a protracted period of time and deal with all issues that arise. If you need that level of help, then you should contract out the service.

Not actually thrown, I will get help later on. But I want to try out myself first. As there are quite a few approaches and tools, I was not sure which one to use. That is why I asked for some tutorials. I do not expect anyone to teach me to step by step procedure. I was trying to get some links for tutorials which are common for beginners. Sorry, if I did not make it clear.
