Since the filter columns were built from dark PVC pipe, the growth of a so-called "Schmutzdecke" (comprising filtered particulate matter and biofilm) could not be observed.
The marker position and force plate data were then exported to Visual3D (C-Motion Inc., Germantown, MD) for further analysis, comprising filtering and inverse dynamics calculation resulting in sagittal joint angles and moments of the hip, knee, and ankle in the stance phase.
These system-level analyses together comprise Filter A. This is then integrated with sequence-level (Filter B) and structural analyses (Filter C) as described below (see Fig. 1).
Class I of the Yonge Nicol system comprises mainly filter feeders; most members of classes II, IIIA, and IIIB are selective feeders.
The remaining portion of the SCE comprises of filter, optocoupler and differential driver for further conditioning of the signal.
From a quarter PicoTitrePlate (PTP) GS-FLX run, a total of 55 million bases of sequence comprising 395,524 filter-pass sequence reads were generated with an average read length of 140 bp after removal of adaptor sequence and splitting of reads into pairs.
Of the 1,625 genes comprising the filtered dataset, we find 1,263 regulated genes and of those, 308 are misregulated in the cli186 mutant [see Additional file 4].
The data set from Altenhein et al. (2006) comprising the filtered and tested genes for the gcm gain of function (GOF) and gcm loss of function (LOF) was retrieved, and all genes giving nonspecific or negative in situ hybridizations (ISHs) were removed to make the Venn diagrams in Figure 2. The R package VennDiagram was used to draw the diagrams in Figure 2, B and C (Chen and Boutros 2011).
The analog baseband is also comprised of filters and gain stages.
The system comprises optical filters, a CCD camera, a frame-grabber and associated software.
