• Introduce a modular software library (SCAN) for high-resolution slit-scan chromosome analysis.
• Enable efficient data acquisition, profile correction, and parameter computation in flow cytometry.
• Provide a flexible platform for detailed chromosome studies using computational methods.

Main Methods:

• Development of a modular program library named SCAN.
• Implementation of single and dual parameter data acquisition using assembler for high input rates.
• Utilizing FORTRAN for software development, allowing for extensions and alterations.
• Real-time histogram calculation and profile correction capabilities.

Main Results:

• Demonstration of SCAN's capability for high-resolution slit-scan chromosome analysis.
• Successful recording and processing of bicolor fluorescence profiles from metaphase chromosomes.
• Efficient data acquisition and real-time histogram computation achieved using a minicomputer system.

Conclusions:

• The SCAN software library provides a robust and flexible solution for advanced chromosome analysis in flow cytometry.
• The developed programs facilitate high-resolution data acquisition and processing, improving the efficiency of genetic studies.
• This computational approach offers potential for enhanced diagnostic capabilities in genetic research.
