FFINDEX_FROM_FASTA(1)

🎀 NAME 🎀

ffindex_from_fasta — bestie, this is the one that populates your index straight from a FASTA file ✨

---

💖 DESCRIPTION 💖

Okay so real talk, here's the whole vibe of how you run this thing:

USAGE: ffindex_from_fasta -v | [-s] data_filename index_filename
fasta_filename

Not me laying out your whole life in one synopsis line 💅. That <italic>data_filename</italic>, <italic>index_filename</italic> and <italic>fasta_filename</italic> trio is literally the whole personality of this command, so hand them over in that exact order, mwah.

Now the flags, and yes we love all of them:

• -s — sorts the index file. it's giving organized queen energy 🗂️✨
• -i — uses the identifier as the name. ngl? you probably want -s alongside this one, they're a package deal 🫶
• -n — uses an incremental number as the id. this is the default, so if you do nothing, this is what you get 😌
• -v — prints the version. short, sweet, iconic 👑

🌸 ENVIRONMENT 🌸

• FFINDEX_MAX_INDEX_ENTRIES — allocates memory for this number of entries. memory go brrr, so pick your number with intention, bestie 🧠💫

Designed and implemented by Andreas Hauser <andy@splashground.de>. the king himself, no cap 👑
