3.00 to 3.01: Major bugfixes and enhancements

  • fixed a major bug in the data grid application ('ui_datagrid.m') that could cause data corruption when editing values using recent versions of MATLAB; due to recent changes in Java-based uicontrol event handling, if a slider was moved after editing a value in a grid cell but before enter was pressed or focus was changed to another cell, the slider position metadata was updated before the update callback was fired, resulting in an offset in grid position that could lead to edits being applied to the wrong cell. A completely new callback approach is now used to ensure updates are always applied before slider events are processed regardless of event order.
  • added new QA/QC functions for flagging numeric values are are either present or absent in an array of allowed values ('inarray.m', 'flag_inarray.m' and 'flag_notinarray.m'); these functions parallel QA/QC functions for text list checks and are useful for QA/QC on numeric code columns

  • relabeled commands in the File menu to improve consistency with the Search Engine menus and commands used by other common applications
  • added a 'Window' menu and new commands for arranging multiple editor windows on the console (cascade, tile and stack windows), as well as selecting an open window to view from a menu listing the titles of all open data sets
  • added new commands to the 'Edit' menu for transforming data columns between data types, casting existing values into the new type using appropriate conversion functions and filters (logging the transform function used in the metadata)
  • added support for choosing open data sets for merge and join operations, allowing data to be integrated on the fly without first saving files to disk or transferring results to the search engine
  • added an automated date/time join option, which identifies compatible date/time columns in two time-series data sets to automatically create join conditions, simplifying the process

    Note: beginning with version 2.80, MATLAB 6.5 (release 13) or higher will be required due to increased dependence on networking and XML features that are not available in prior versions

2.63c to 2.70: Bug fix in 'ui_harvestclimdb' to properly enable the 'Proceed' button after all fields are filled in when the dialog is run for the first time without a saved settings file. Significant enhancements and new features, including:

  • reconfigured options on the Editor window 'Tools' menu to simplify finding dialogs for various data transformation and analysis tasks ('ui_editor')
  • added a new function and Editor window command for splitting a compound data series on values in a specified column, and then joining the split columns on other specified data columns to create a normalized data table (e.g. splitting records from a merged data set on column 'Site', creating separate 'Salinity' and 'Temperature' columns for each value in 'Site', and joining split 'Salinity' and 'Temperature' columns on date/time columns 'Year','Month','Day','Hour','Minute' to create a tabular data set with separate columns for observations from each site) ('split_dataseries')
  • added new command-line data mining functions for retrieving National Estuarine Research Reserve data from the NOAA/NWS Hydrometeorological Data System ('fetch_nerr_data', 'parse_nerr_data')
  • numerous usability improvements, including automatically recalling the most recent settings used on plotting dialogs and automatically prompting users to download a pre-compiled search index for GCE web-based data sets when starting the 'Search Engine' application for the first time

2.63b to 2.63c: Minor bug fixes and refinements to 'imp_ascii' to prevent problems parsing ClimDB information files; changes to Q/C rules for generated date component columns in 'add_datepartcols' to improve flagging logic; enhancements to 'ui_visual_qc' to support closing all plotting dialogs after manually-updating QA/QC flags (i.e. closing dialogs containing cached copies of the outdated structure); updates to USGS metadata templates to remove duplicate attribute metadata references; bug fixes in polygon editing functions in mapping tools 'edit_poly' and 'poly_mgr'

2.63 to 2.63a: bug fix in 'dataflag' to correct an issue that prevented clearing residual flags after flagged values were changed or removed under certain circumstances

2.62 to 2.63: Modifications to USGS data processing functions ('parse_usgs', 'fetch_usgs', 'ui_harvestusgs') and metadata templates to accommodate revised format of daily data provided by the USGS NWIS web applications (i.e. flagging of all data values as accepted (_A) or provisional (_P) in addition to other flags such as _e for estimated value, etc). Note that accepted flags are automatically removed from processed data for compatibility with the GCE Data Toolbox Q/C flagging scheme, and provisional value flags are also removed but a coded 'Provisional' column is added to indicate that records contain values flagged as provisional by USGS. Other flags (e.g. 'e' for estimated value) are converted to text flag columns and are automatically merged with rule-based flags assigned by attribute Q/C criteria.

2.61 to 2.62: minor enhancements, including:

  • updated default ClimDB/HydroDB url in 'ui_harvestclimdb' and 'ui_harvestclimdb.mat'  in response to web address changes at OSU

  • added support to 'fetch_usgs' for automatically adding USGS station metadata (coordinates, altitute, drainage area) when the generic metadata template (USGS_Generic) is used; package also includes an updated USGS stations data set ('usgs_stations.mat') containing new data fields Longitude, Latitude, Altitude and Drainage
  • refactored compiler code to ensure .p files are new than corresponding .m files to prevent warning messages using MATLAB R13+
  • fixed an index error in 'add_anomalies', which caused the incorrect columns to be listed in the processing history under certain circumstances

2.53 to 2.54: minor enhancements and bug fixes, including:

  • added a user-selectable option in 'ui_aboutgce' to automatically re-open the startup dialog if both the data editor and search engine dialogs are closed and no other dialogs are open (i.e. last window closed) - this will prevent GUI users from having to interact with the MATLAB command window

  • updated 'plotdata' and 'plotgroups' to improve handling of empty data columns to avoid generation of empty plots or empty data series, and to improve handling of large title strings (i.e. now restricted to 3 lines of text)
  • updated 'ui_plotdata', 'ui_plotgroups' and 'ui_mapdata' to support comprehensive data restriction queries instead of just single column restrictions; full query statements can now be entered in plotting dialogs to filter values prior to plotting, and query statements can be entered /edited manually or by using the graphical query builder dialog ('ui_querybuilder')
  • updated 'ui_querybuilder' to support parsing query statements to populate dialog controls and to return edited query statements to calling functions instead of executing the query and returning a data set (i.e. to support data restriction query building/editing for plotting dialogs)

2.10 to 2.20: updated 'ui_search_data' and 'multimerge' to restore support for Q/C flag removal prior to data set merging (broken in 2.01); significant enhancements to the GCE Data Search Engine components, including:

  • updated 'search_index', 'search_data' and 'ui_search_data' to load configuration information stored in a common file ('search_data.mat') to support end-user extension and customization of metadata content that is indexed and searched (e.g. add/edit metadata fields and field mappings, change text comparison options)
  • added support for simultaneously searching the contents of all indexed metadata fields (i.e. 'Any Text Contains') to 'search_data' and 'ui_search_data'
  • updated the metadata field selector in 'ui_search_data' to display the text comparison type along with the metadata field (e.g. 'Abstract Text Contains' or 'Accession Begins With')

2.06 to 2.10: minor bugfix in 'get_studydates' to handle text date conversion issues in MATLAB 5.3; significant enhancements to metadata management/display functions, including:

  • enhancements to 'ui_editmetadata' to support overlaying or overwriting metadata with only selected metadata fields from an existing data structure (i.e. instead of all fields) for fine-tuning metadata content re-use (brings 'ui_editmetadata' in line with metadata importing in 'ui_editor')
  • enhanced 'listmeta' by simplifying the metadata style definition syntax, adding support for metadata field placeholders in text expressions and thereby eliminating the requirement for MATLAB character array syntax when referencing multiple metadata fields (Note: unfortunately, this change also eliminates support for MATLAB text functions in style definitions for auto-generating metadata, e.g. 'datestr(now)')
  • updated all styles in 'metastyles.mat' to support the new 'listmeta' syntax
  • updated 'listhist' to improve performance when formatting large processing history arrays

2.05 to 2.06: NOTE: Version 2.06 is the first public release of version 2.x and contains various bug fixes and enhancements, including:

  • bug fixes and enhancements in 'flag_valuechange' and 'flag_percentchange', including new option to recursively analyze flag conditions to minimize flagging of normal-range values following flagged outliers
  • bug fixes in 'ui_gce_register' and 'ui_search_data' to prevent inappropriately storing user registration information in the default workspace file when 'Store my registration information on this computer' was not checked (registration is still stored in manually created workspace files)
  • enhancements to metadata and text viewer dialogs to support figure resizing ('ui_viewtext', 'ui_viewmeta'), text file export ('ui_viewtext', 'ui_viewmeta', 'ui_viewdocs') and text file import ('ui_viewtext') -- users can now save formatted metadata, data processing histories and toolbox documentation to disk for their own use outside of MATLAB
  • enhancements to 'add_anomalies' to support documenting flagged and missing values only in user-selected data columns (now set as default when function called from 'ui_editor')
  • Note: the public version of the toolbox (gce_datatools_206public.zip) has some GCE-specific import filters, batch scripts and metadata templates removed, but is otherwise complete

2.04 to 2.05: minor bug fix in 'joindata'; various program enhancements and additions, including:

  • significant performance improvements in the GCE Data Search Engine ('search_data') due to improved query optimization, resulting in up to 10-fold faster searches when numerous criteria are specified
  • major speed improvement in refreshing search indices due to improvements in file modification checking that minimize loading files into memory
  • enhanced the GCE Data Search engine dialog ('ui_search_data') to support viewing the contents of each indexed path (i.e. file name, modification date, title)
  • added a GUI dialog for exporting climate and hydrographic data sets as text files in the LTER ClimDB/HydroDB format, as well as viewing/editing corresponding attribute name and unit mappings ('ui_expclimdb', based on 'exp_climdb')
  • improvements to 'flag_valuechange' and 'flag_percentchange' routines for flagging value changes relative to prior values or running averages

2.03 to 2.04: enhancements to 'fill_date_gaps' to support time series data sets with small numbers of duplicated values, and enhancements to 'search_index' and 'search_data' to support indexing and searching on column units and variable types in addition to names and also searching on column name + units

2.02 to 2.03: major bug fix in 'add_datepartcols' to correct generation of hour=24 values after rounded seconds propagated to minutes and hours, causing difficulties with date/time aggregation due to mixed hour=0 and hour=24 values in a single data set (seconds are now truncated when not included in the output columns); added logic to 'aggr_datetime' to automatically regenerate date component columns when a serial date column is present to avoid this issue with legacy data sets containing mixed hour=24 and hour=0 values.

2.01 to 2.02: minor bug fixes in 'ui_search_data' and 'mergemeta'

2.00 to 2.01: enhancements to data integration functions and the Data Search Engine GUI application, including:

  • improved merging of data release dates and keywords in metadata ('mergemeta')

  • changed keyword search logic in 'search_data' from partial string match to beginning string match and added code to prevent reverse matches when keywords being searched are shorter than the search term (i.e. to prevent spurious results such as matching 'par' on searches for 'Spartina' or vice versa)
  • added new multiple dataset merge function ('multimerge') that supports merging (i.e. contatenating) data sets based on a file list and structure name list to support merging structures stored in multiple directories as well as structures contained in compound files; also supports 3 merge types (listed order, study date order, non-overlapping study date order) and various metadata merge options
  • added support for the new 'multimerge' function options to 'ui_multimerge' and 'ui_search_data' to provide more flexible data integration options from GUI programs
  • changed default startup mode of 'ui_search_data' to initially hide the Query History pane to simplify the form
