Split fastq file with renaming reads

[empyrean]

Hi

I am trying to split fastq file to one read per file seperately and rename the read name. For example

@HBGAIY001A
TGTCTCAACTAATTTAGCCGCAGACCAAGTCTCTGCTACCGT
+HBGAIY001A
III???HIHG<<???EEEEE?BBF9999?EEEF>@@AEAA?999:=II
@HBGAIY001A
GGAACATGAACAGACCAAGTCTCTGCTACCG
+HBGAIY001A
4400/67766724/0088??AAAA???FFFFFFFC

The above is example for two reads and i have big file with reads. Now i wanted to make them in to seperate file i.e here two files and rename the read name. After that it should be like this

File 1:

@Sample1_HBGAIY001A
TGTCTCAACTAATTTAGCCGCAGACCAAGTCTCTGCTACCGT
+Sample1_HBGAIY001A
III???HIHG<<???EEEEE?BBF9999?EEEF>@@AEAA?999:=II

File 2:

@Sample1_HBGAIY001A
GGAACATGAACAGACCAAGTCTCTGCTACCG
+Sample1_HBGAIY001A
4400/67766724/0088??AAAA???FFFFFFFC

You need to learn a scripting language: bash, perl ,python or a higher level language C,C++,java. Meeting your specification is trivial using these tools.
I'd recommend figuring out bash and the standard UNIX utilities (sed/grep/awk/tr) because if you succeed, your going to need them for de-complicating your life.

But ...
You don't want to do what you are suggesting. Fastq files are very large. I mean ... MUCHO GRANDE ... HUGEMONGOS number of records. Imagine creating a file for every record. Result: too many files. It's damn near impossible to manage tens of thousands of files. Even listing the files just to see what's in a directory becomes very difficult. Are you going to scroll for 9 minutes trying to find a record?

There's probably better paths to reaching your goal.
