Minor bug fixes. Fixed bugs that caused crashes related to the new NCBI structure format.

November 8, 2016

Updated for iOS 10, fixes minor bug in displaying structures immediately after downloading from the MMDB (NCBI) or from the PDB. Also fixes minor bug in displaying PDB files when downloaded from website.

- Color and draw proteins to show secondary structure elements (beta sheets, alpha helices, and coils) - Use the color key to identify secondary structure elements - Improved ability to search for sequences - Added ability to use a wild card character (*) in a sequence search - Improved rendering for large structures like antibodies, that download as alpha carbons. - View a wider range of PDB files. - Added ability to show thorium - Fixed a bug where alpha carbon structures were not displayed on initial download

New rendering styles: backbone view with side-chains hidden, backbone view with oxygens hidden Identify binding sites for other molecules, drugs, or small chemicals by selecting nearby residues Search and select sequences by pattern or one letter code Use mixed drawing and coloring modes Improved coloring for smaller chemicals (water, glucose, etc.)

- An adaptive sequence viewer displays DNA, RNA, and protein sequences and other chemicals - Protein, DNA, or RNA chains, single residues, and other chemicals (coenzymes, metals, or drugs) can be selected and highlighted from the sequence viewer - The sequence viewer allows any object in a structure to be highlighted, dimmed, or hidden - Rainbow coloring shows where amino acids or nucleotides are located within a chain and helps illustrate protein and RNA folding - Instant recoloring from the visualization menu - Expanded information view - Improved display of bonds to metals, drugs, and disulfide bonds - Improved search - Structures are now downloaded from the NCBI (MMDB) as biological units - Structures from the PDB are downloaded as asymmetric units - View large, complex, structures (< 120,000 atoms) - Minor bug fixes
