How would I go about converting to NewPGen format to .abcd for sr(x)sieve
Also, should I use srsieve or sr2sieve?

You don't need to convert to .abcd format.

Neither. You should use sr1sieve, which sieves only one k at a time at very high speed. It needs the file in NewPGen format.

For future reference, if you need to convert from NewPGen to .abcd format, use srfile with the following command:
srfile -a filename.txt

Can someone teach me how to remove any lines below n=5k and those with factors found? I'm using Win64pfgw for testing.

If further sieving is needed, there are 3 steps involved because you need to have the file in NewPGen sieve format for removing n-values. Do this:

1. To remove factors, run srfile with the following command:
srfile -G -k factorfile.txt sievefile.txt
This will both remove factors and write it out in NewPGen sieve format.

2. The file in #1 will now be in n-value order. Just manually remove all n < 5000.

3. Using the file in #2, get it back into ABCD format for further sr2sieve sieving:
srfile -a (filename from #2).

If you are done sieving, you can skip #3, change the header from the file in #2 to ABC format with the stop-on-prime option, and start testing.

Edit: This is the way I do it but I think others have used PFGW format, i.e. with the -w instead of -G switch. This would probably put the header in ABC format but I think you'd still have to add the stop-on-prime option.

Does "factorfile.txt" need a header to work?
