cufCDS calculates codon usage frequency (CUF) of coding sequences (CDSs). The input of this application is a fasta file of coding sequences. The application removes CDSs that are not divisible by 3 and counts the codons of each CDS after removing the start and stop codons. The result for each CDS is reported in the .gcf file. The following files are also produced: .fss, which reports the frequencies of codons used as start and stop signals .lss, which contains the list of start and stop codons of each gene. .cuf, which reports the total frequencies and the fraction of synonymous codons.

...The profile is obtained by calculating the genome-wide Pearson correlation coefficient (R) between the genomic variable values and the TSS (or TTS) counts at incremental shifting of transcribed strand. The data of TSS and TTS counts used to compute the profiles were taken from the work of Pelechano et al. (1). The input file must be a BedGraph formatted file based on yeast genome sequence release R64. The output file is a text tab-delimited table reporting R values for the various shifts of variable coordinates with respect to TSS or TTS. R related to each strand is also reported to verify that a similar profile is obtained in the two direction of transcription. 1) V. ...

...The random permutation is obtained using a simple variation of the Fisher-Yates alghorithm implemented by Durstenfeld (https://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle) ( Knuth DE. The art of computer programming: seminumerical algorithms. 3rd ed. Boston: Addison-Wesley; 1997). The input file contains one or more sequences in FASTA format. The number of shufflings (n) for each sequence can be set; by default n is 100. The output file contains n shuffled copies in FASTA format for each input sequence. For example (n=3): Input file: >a ACGGT >b GCCCATTC Output file: >a TCGAG >a CGAGT >a TGCGA >b CACTCCGT >b CCCGTATC >b CCTTCAGC

BLAST (Basic Local Alignment Search Tool) is a popular program that retrieves a library of sequences that resemble the query. The major problem experienced by new users of BLAST revolves around constructing syntactically and semantically correct command line, getting input files into acceptable formats and assessing the output. Visual BLAST is a Graphical User Interface written in C# and it was developed to simplify the parameters setting for BLAST searches. Visual BLAST aims to make BLAST searches accessible to a wider audience with no bioinformatics skill and to facilitate usage among the existing. ...
