Use pdfplumber to extract text from PDFs:
import pdfplumber
with pdfplumber.open("document.pdf") as pdf:
text = pdf.pages[0].extract_text()
print(text)
Extract tables from PDFs with automatic detection:
import pdfplumber
with pdfplumber.open("report.pdf") as pdf:
page = pdf.pages[0]
tables = page.extract_tables()
for table in tables:
for row in table:
print(row)
Process multi-page documents efficiently:
import pdfplumber
with pdfplumber.open("document.pdf") as pdf:
full_text = ""
for page in pdf.pages:
full_text += page.extract_text() + "\n\n"
print(full_text)
For PDF form filling, see FORMS.md for the complete guide including field analysis and validation.
Combine multiple PDF files:
from pypdf import PdfMerger
merger = PdfMerger()
for pdf in ["file1.pdf", "file2.pdf", "file3.pdf"]:
merger.append(pdf)
merger.write("merged.pdf")
merger.close()
Extract specific pages or ranges:
from pypdf import PdfReader, PdfWriter
reader = PdfReader("input.pdf")
writer = PdfWriter()
# Extract pages 2-5
for page_num in range(1, 5):
writer.add_page(reader.pages[page_num])
with open("output.pdf", "wb") as output:
writer.write(output)
Extract and save text:
import pdfplumber
with pdfplumber.open("input.pdf") as pdf:
text = "\n\n".join(page.extract_text() for page in pdf.pages)
with open("output.txt", "w") as f:
f.write(text)
Extract tables to CSV:
import pdfplumber
import csv
with pdfplumber.open("tables.pdf") as pdf:
tables = pdf.pages[0].extract_tables()
with open("output.csv", "w", newline="") as f:
writer = csv.writer(f)
for table in tables:
writer.writerows(table)
Handle common PDF issues:
import pdfplumber
try:
with pdfplumber.open("document.pdf") as pdf:
if len(pdf.pages) == 0:
print("PDF has no pages")
else:
text = pdf.pages[0].extract_text()
if text is None or text.strip() == "":
print("Page contains no extractable text (might be scanned)")
else:
print(text)
except Exception as e:
print(f"Error processing PDF: {e}")
Convert raw Nanopore signal data (FAST5/POD5) to nucleotide sequences using Dorado basecaller. Covers model selection, GPU acceleration, modified base detection, and quality filtering. Use when processing raw Nanopore data before alignment. Guppy is deprecated; use Dorado for all new analyses.
Production-ready PDF processing with forms, tables, OCR, validation, and batch operations. Use when working with complex PDF workflows in production environments, processing large volumes of PDFs, or requiring robust error handling and validation.
Analyze protein-protein interaction networks using STRING, BioGRID, and SASBDB databases. Maps protein identifiers, retrieves interaction networks with confidence scores, performs functional enrichment analysis (GO/KEGG/Reactome), and optionally includes structural data. No API key required for core functionality (STRING). Use when analyzing protein networks, discovering interaction partners, identifying functional modules, or studying protein complexes.
Prepare for US medical licensing exams with progress tracking, weak area analysis, question bank management, and residency match planning.
Validate protein designs using AlphaFold2 structure prediction. Use this skill when: (1) Validating designed sequences fold correctly, (2) Predicting binder-target complex structures, (3) Calculating confidence metrics (pLDDT, pTM, ipTM), (4) Self-consistency validation of designs, (5) Multi-chain complex prediction with AlphaFold-Multimer. For faster single-chain prediction, use esm. For QC thresholds, use protein-qc.
End-to-end binder design using BindCraft hallucination. Use this skill when: (1) Designing protein binders with built-in AF2 validation, (2) Running production-quality binder campaigns, (3) Using different design protocols (fast, default, slow), (4) Need joint backbone and sequence optimization, (5) Want high experimental success rate. For backbone-only generation, use rfdiffusion. For QC thresholds, use protein-qc. For tool selection guidance, use binder-design.
