You could use the Roche/454 Amplicon Variant Analyzer software. The software is designed for processing and analyzing ultra-deep amplicon sequence data from the GS FLX system. It will read the SFF file directly and can be used via either a GUI or command line.
Roche/454 software can be obtained by request through their web site:

If it is the SFF format that is worrying you, you can convert SFF into FASTQ or FASTA+QUAL which are more widely supported. I can suggest three tools for that,
Roche's own "off instrument applications" (Linux only)

Biopython's SeqIO module - http://biopython.org (cross platform)

454 Sequences analysis!!
Hi everybody!!!
I am trying to analyze some amplicons sequences from 454, but I need some advice. I need to find SNP in my sequences, synonym substitutions and non synonym and haplotypes; but I don’t know what kind of programs can I use? Mainly because of the .sff file format from my sequences.
I hope someone could help me
Thanks in advance

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-
