Luaces, Miguel; Pedreira, Oscar In 2015, our research laboratory started the definition and implementation of a Software Product Line (SPL) for the generation of web-based Geographic Information Systems. Tooling support for SPL was scarce, and we did not found any suitable alternative to implement the mentioned product line. Therefore, we built spl-js-engine, a JavaScript library that, following the annotative approach, can generate final product source code from the annotated code, the feature model of the product line, and a product specification. spl-js-engine validates the specification of the product against the feature model prior to the generation. Since its first implementation, we have used this tool in many occasions both in the academia and the industry contexts.

Paramá, José; Salmela, Leena During viral infection, intrahost mutation and recombination can lead to significant evolution, resulting in a population of viruses that harbor multiple haplotypes. The task of reconstructing these haplotypes from short-read sequencing data is called viral quasispecies assembly, and it can be categorized as a multiassembly problem. We consider the de novo version of the problem, where no reference is available. We present ViQUF, a de novo viral quasispecies assembler that addresses haplotype assembly and quantification. ViQUF obtains a first draft of the assembly graph from a de Bruijn graph. Then, solving a min-cost flow over a flow network built for each pair of adjacent vertices based on their paired-end information creates an approximate paired assembly graph with suggested frequency values as edge labels, which is the first frequency estimation. Then, original haplotypes are obtained through a greedy path reconstruction guided by a min-cost flow solution in the approximate paired assembly graph. ViQUF outputs the contigs with their frequency estimations. Results on real and simulated data show that ViQUF is at least four times faster using at most half of the memory than previous methods, while maintaining, and in some cases outperforming, the high quality of assembly and frequency estimation of overlap graph-based methodologies, which are known to be more accurate but slower than the de Bruijn graph-based approaches.

Brisaboa, Nieves; R. Penabad, Miguel; S.Places, Ángeles; Rodríguez, Francisco J. There has been lately much effort put on the creation of digital libraries containing antique documents, in order to preserve our cultural heritage and provide a broader access to them, but they are usually isolated one from another. This work presents a system, based on the use of XML trees, to federate three existing digital libraries that contain documents from the Spanish Golden Age (16th-18th centuries). This federation offers very valuable advantages to a wide community of researchers, who will be able to access (at present time, three) databases of historic documents through a unique entry point.
