In biomedical sciences, there are currently > 24 million citations in the MEDLINE database alone ( 1). Science has become a highly specialized endeavor and the total number of published papers has dramatically increased in the last decades. Here, we have described a simple reproducible method for extracting data from graphs using Adobe Photoshop.Īdobe Photoshop Data Extraction Graph Meta-Analysis. In this case, there are a few software and methods that may be used for data extraction however, using these software is costly and not simple as well as different types of graphs need different extraction methods. On the other hand, contacting the authors of a particular publication in order to retrieve the data may take a long time and is often not very fruitful. Since this kind of results presentation is common, ignorance of such data may result in publication bias when conducting meta-analyses. Extracting numerical data from graphs, which is commonly required in systematic reviews and meta-analyses, is however a challenging issue. Raster Scan Mode (scatter plots, drawings, etc.Graphs, an effective form of data presentation, are used for summarizing complex information and making them easier to understand.Semi‑Automatic Mode (multiple curves, intersecting curves, charts, drawings, etc.).Automatic Line Follow Mode (spectra, chromatograms, strip charts, thermograms, etc.).Colored and Grayscale Image Recognition.Linear, Semi-Log, and Logarithmic Scales.Image digitizing of JPG, TIFF, GIF, BMP, PNG and other image formats.Automatic Digitizing at up to 10,000 data points per minute.Interactive cursors allow data editing, peak location, and peak area integration.Export xy data to other spreadsheet, data analysis, and graphics programsĪlthough the UN-SCAN-IT Software has many options and features, the basic operation simply consists of automatically converting an image (JPG, TIFF, GIF, BMP, PNG, etc.) into useful (x,y) values through a few simple graph digitizing steps.Save the data in (x,y) ASCII text, JCAMP, and clipboard format.Prepare publication quality graphs from messy originals.Analyze and store hard copy graphs in digital (x,y) format.Graph data, subtract background, smooth data, fit data, etc.Re‑scale and append existing hard copy graphs.Use any scanner like an xy digitizer tablet.Find peak areas without using the "cut and weigh" technique.Digitize old graphs and plots for comparison with new data.Compare your data with published graphs of other investigators.Compare and analyze data from graphs that are on different scales.Automatically digitize strip chart and xy recorder output.Convert hard copy graphs, plots, and charts into real (x,y) data.Digitizing graphs and plots with the UN‑SCAN‑IT program is accurate, quick, and easy. you no longer need to guess at data values, use light tables to compare the features, count squares to find peak areas, or "point and click" on data points with a digitizing tablet. If you need to get data from graphs or charts. In addition to the many graph and chart digitizing features, UN‑SCAN‑IT also integrates peak areas, smoothes data, takes derivatives, re‑scales graphs, and exports (x,y) data for use in other software. UN‑SCAN‑IT works with most image formats (JPG, TIFF, GIF, BMP, PNG, etc.) from any scanner, digital camera, or other image source to digitize data from strip charts, instrumental output, old graphs, published graphs, etc. The UN-SCAN-IT Graph Digitizer Software converts graph image files to usable (x,y) data automatically.
