Web10 mrt. 2024 · Prior to 3DEC Version 7, it was only possible to import blocks (not zones). Complicated geometries were created by importing an assembly of tetrahedral blocks. Most of the time, most of these blocks are joined – the contacts between them are not true faults. This is very inefficient and uses up a lot of memory and slows down the computations. WebWhy convert the format? In order to make the computer easy to handle. The SAM (sequence Alignment/mapping) data format is the current standard format for storing alignment data in high-throughput sequencing. Bam is the binary format of sam, which reduces the storage capacity of sam files. 2. Main functions of SAMTools
