bio-write-sequences
Write biological sequences to files (FASTA, FASTQ, GenBank, EMBL) using Biopython Bio.SeqIO. Use when saving sequences, creating new sequence files, or outputting modified records.
npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill bio-write-sequences --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
## Version Compatibility Reference examples tested with: BioPython 1.83+, pysam 0.22+, samtools 1.19+ Before using code patterns, verify installed versions match. If versions differ: - Python: `pip show <package>` then `help(module.function)` to check signatures If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying. # Write Sequences **"Write sequences to a file"** → Serialize SeqRecord objects into a formatted sequence file. - Python: `SeqIO.write()` (BioPython) - R: `writeXStringSet()` (Biostrings) Write SeqRecord objects to sequence files using Biopython's Bio.SeqIO module. ## Required Import ```python from Bio import SeqIO from Bio.Seq import Seq from Bio.SeqRecord import SeqRecord ``` ## Core Functions ### SeqIO.write() - Write Records to File Write one or more SeqRecord objects to a file. ```python SeqIO.write(records, 'output.fasta', 'fasta') ``` **Parameters:** - `records` - Single SeqRecord, list, or iterator of SeqRecords - `handle` - Filename (string) or file handle - `format` - Output format string **Returns:** Number of records written (integer) ### record.format() -

What does the bio-write-sequences skill do?
Write biological sequences to files (FASTA, FASTQ, GenBank, EMBL) using Biopython Bio.SeqIO. Use when saving sequences, creating new sequence files, or outputting modified records.
How do I install it?
Run `npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill bio-write-sequences --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From FreedomIntelligence/OpenClaw-Medical-Skills, a repository with 2,909 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
