Putative domain linkers and low-complexity regions assigned in SWISSPROT sequences. Each thick black horizontal bar represents a SWISSPROT sequence used as a test sequence. The SWISSPROT ID number is indicated on the top left of the corresponding sequence. In each SWISSPROT sequence, sequence regions similar to PDB and CDD sequences were assigned as putative structural domains. A green horizontal bar represents a sequence region similar to a PDB sequence. Similarly, the horizontal bars colored in blue, red and magenta represent sequence regions similar to CDD sequences, corresponding to the Pfam, SMART and LOAD (Library Of Ancient Domains) libraries, respectively. Sequence regions predicted to be putative domain linkers are designated by vertical bars in colors ranging from yellow to brown, according to the neural network output values. Low-complexityregions are designated by cyan rectangles overlaid on black bars.
