structures. Research has also used data on everyday work activity sequences to identify classes of work schedules, finding that the timing of work during the day significantly affects workers' abilities to maintain connections with the broader community, such as through community events. More recently, social sequence analysis has been proposed as a meaningful approach to study trajectories in the domain of creative enterprise, allowing the comparison among the idiosyncrasies of unique creative careers. While other methods for constructing and analyzing whole sequence structure have been developed during the past three decades, including event structure analysis, OM and other sequence comparison methods form the backbone of research on whole sequence structures. Some examples of application include: Sociology Labor market entry sequences De-standardization of the life course Residential trajectories Time use Actual and idealized relationship scripts Basic types of figures in ritual dances Pathways of alcohol consumption Demography and historical demography Transition to adulthood Partnership biographies Family formation life course Childbirth histories Political sciences Pathways towards democratization Pathways of legislative processes Bargaining between actors during national crises Psychology Sequences of adolescences' social interactions Medical research Care trajectory in chronic disease Survey methodology Response in survey collection Geography Mobility studies Land use Software Two main statistical computing environment offer tools to conduct a sequence analysis in the form of user-written packages: Stata and R. Stata: SQ and SADI are general SA toolkits. MICT is dedicated to imputation of missing elements in sequences. R: TraMineR with its extension TraMineRextras is probably the most comprehensive SA toolkit; ggseqplot, provides ggplot versions of most TraMineR plots; seqhandbook provides several specific tools such as heat maps of sequence data and the GIMSA method for measuring dissimilarities between multidomain sequences; seqimpute provides tools for imputing missing elements in sequences; seqHMM, although specialized in fitting Markov models, this package provides useful plotting facilities for rendering multichannel sequences and transition probabilities; WeightedCluster versatile clustering package with original tools for grouping identical sequences and rendering hierarchical trees of sequences; PST fits and renders probabilistic suffix trees of sequences. Institutional development The first international conference dedicated to social-scientific research that uses sequence analysis methods – the Lausanne Conference on Sequence Analysis, or LaCOSA – was held in Lausanne, Switzerland in June 2012. A second conference (LaCOSA II) was held in Lausanne in June 2016. The Sequence Analysis Association (SAA) was founded at the International Symposium on Sequence Analysis and Related Methods, in
