Sequence comparison by alignment is a fundamental tool of molecular biology. In this paper we show how a number of sequence comparison tasks, including the detection of unique genomic regions, can be accomplished efficiently without an alignment step. Our procedure for nucleotide sequence comparison is based on shortest unique substrings. These are substrings which occur only once within the sequence or set of sequences analysed and which cannot be further reduced in length without losing the property of uniqueness. Such substrings can be detected using generalized suffix trees. We find that the shortest unique substrings in Caenorhabditis elegans, human and mouse are no longer than 11 bp in the autosomes of these organisms. In mouse and human these unique substrings are significantly clustered in upstream regions of known genes. Moreover, the probability of finding such short unique substrings in the genomes of human or mouse by chance is extremely small. We derive an analytical expression for the null

Friday, September 4. Psalm 31: The correct sense of Psalm 31 (Greek and Latin 30) is indicated in verse 5: Into Your hand I commend my spirit. This verse, according to Luke 23:46, was the final prayer of our Lord from the Cross, and I take it to indicate the proper voice of this whole psalm. It is the prayer of Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame (Heb. 12:2), speaking to His Father in the context of His sufferings and death. This psalm is part of His prayer of faith.. In making this psalm our own, we Christians are subsumed into the voice and prayer of Christ. We partake of His own relationship to the Father. No one, after all, knows the Father except the Son and the one to whom the Son wills to reveal Him (Matt. 11:27). Our only access to God is through Christ and the mediation of His atoning blood. Our incorporation into Christ is the foundation of all our prayer. Only in Christ do we call God our ...
Over the last ten years the amount of biological sequence data available to researchers has increased by several orders of magnitude, and complete genome sequences (nearly nonexistent ten years ago) have become commonplace. Some techniques involved in analyzing nucleotide and amino acid sequences (e.g. BLAST) have become so commonly used in molecular biology that their names have become verbs. This introductory course is aimed at biologists with little or no previous experience, but also at those users who wish to know more about the methods underlying computational sequence analysis tools. Learn how to use the tools at the European Bioinformatics Institute (EBI/EMBL) to find out more about your nucleotide and protein sequences. You will be guided through a series of exercises using sample fragments of sequence. To gain more information about these sequences, you will use a variety of tools to compare the sequences to databases to analyse them ...

For #4 you probably would need to create a custom script, because I do not think this is supported by those tools (this feature would probably need to be very flexible and would need to allow substrings of custom length, not only length 2 substrings ...
Suffix arrays and their variants are used widely for representing genomes in search applications. Enhanced suffix arrays (ESAs) provide fast search speed, but require large auxiliary data structures for storing longest common prefix and child interval information. We explore techniques for compressing ESAs to accelerate genomic search and reduce memory requirements. We evaluate various bitpacking techniques that store integers in fewer than 32 bits each, as well as bytecoding methods that reserve a single byte per integer whenever possible. Our results on the fly, chicken, and human genomes show that bytecoding with an exception guide array is the fastest method for retrieving auxiliary information. Genomic searching can be further accelerated using a data structure called a discriminating character array, which reduces memory accesses to the suffix array and the genome string. Finally, integrating storage of the auxiliary and discriminating character arrays further speeds up genomic search. The
One example I have of this took place just this past season. A freshmen and 1st year wrestler was having a difficult time. He was not wrestling much, and when he did get a chance, he lost quickly. He was looking dejected and I took a moment to speak with him. I asked him if he remembered his first week of practices, how he could not do the push-ups, keep up on the run, and how sore he was the day after practice. He said yes, and then I reminded him how today he was doing the push-ups, and keeping up on the runs. I let him know he had already lost almost 20 pounds, while getting stronger. As a smile started to creep across his face, I saw that he got it. He got the idea of the long haul of work paying off, over time. He could see the progress and make the link to his hard work all season. He liked it.. His improvement over time was not only limited to his physicality. He has opened up more among his peer group. He is walking taller, smiles more quickly, and is improving academically with much ...
A set of words of a natural language is grouped by automatically obtaining suffix relation data that indicate a relation value for each of a set of relationships between suffixes that occur in the natural language, and, then, by automatically clustering the words in the set using the relation values from the suffix relation data, to obtain group data indicating groups of words. Two or more words in a group have suffixes as in one of the relationships and, preceding the suffixes, equivalent substrings. The relationships can be pairwise relationships, and the relation value can indicate the number of occurrences of a suffix pair. The suffix relation data can be obtained using an inflectional lexicon. Complete link clustering can be used.
SADI is a suite of Stata tools for sequence analysis, with a particular focus on holistic comparisons of sequences using measures such as optimal matching distance. It provides a number of distance measures, including • Optimal matching distance • Hamming distance • Dynamic Hamming distance • Elzingas combinatorial X/t measure and • TWED, a time-warping distance measure. It provides a number of utilities for graphing sequence-related data, for summarising sequences, and for handling sequences in general. The main alternatives to SADI are the Stata SQ package (Brzinsky-Fay, Kohler&Luniak, 2006), and the R package TraMineR (Gabadinho, Ritschard, Studer & Müller, 2009). SADI provides some tools that are not in SQ, and is much faster for some important functions. TraMineR is pretty attractive for those working in R, but SADI makes it possible to do a lot in a Stata environment, and has distance measures that are not in TraMineR. Since some of the distance measures are relatively ...

Hi guys, Back from a sunny and warm long weekend, let me continue our discussion on framework design and implementation based on Koens input. Let me start by proposing an idea which again is derived from the BioJava framework. I think also in this respect they must have had a similar discussion as we are having here, and I see there solution to the problem as a very nice one. First an explanation of the idea, then my thoughts in this light as a reply to the things brought up. Basically we have two options: either go for a string based solution (as sequences are kind of long strings in the end), or go for a specific sequence class approach. As outlined in the link above, the string based approach has some clear disadvantages: 1 One would constantly need validation of strings as they allow non existing characters. I use strings in my programs to store sequences (I bet everyone does) and I constantly strip foreign characters upon editing, copying, dragging etc, in fact thats how I call my ...

In this paper, we investigate the chaotic behavior of the biological sequences among the different species. Throughout this work, we have characterized the biological sequences according to their moment invariant, correlation dimension, and largest Lyapunov exponent estimates. We have applied our model to a number of human and mouse genomes encoded into a set of integers (time series) using a plain table mapping scheme. Our results indicate that the nonlinear dynamical characteristics have yielded significant differences between the sequences of the different species. That is, we have been able to classify the different genome sequences according to their chaotic parameters estimates. On the other hand, through our investigation we have found that the use of the chaotic modeling of the biological sequences could open new frontiers in the sequence similarity search ...
