Dedoose is an easy-to-use, collaborative, web based application that facilitates all types of research data management and analysis.
Here's what you need to know about how to use it.
The Dedoose Code Tree is flexible, dynamic, and rich with features. Thoughtful use of code definition and weighting systems and the structure of the code tree will be central to the value of your work. Note that we use the terms 'code' and 'tag' interchangeably in Dedoose. While codes and tags may be understood to represent different things, their functionality in Dedoose is identical. Code specific editing controls appear when floating the cursor over an existing code and clicking the 'edit code' icon.
Above the Code Tree on the right are four buttons that will help you arrange and control how codes function as you work. The first button going left to right will be a magnifying glass that will search the code tree for a keyword. Second is the settings panel where you will find these functions:
The third button is the Actions Panel:
The fourth and final button is for adding a new code. When adding a new code to the tree, you are presented with the ability to provide a title, descriptor, and activate (and set parameters for) a code rating/weighting dimension. Note that all of this information will show up as a smart-tip when floating over the code, so is a good place to note any tips or reminders on how to use the code.
Editing an Existing Code
When in code tree editing mode, you can float over an existing code to view options to link a memo, edit the code, or add a root code. When editing the code you will see options to edit the initial information provided when creating the code as well as buttons to:
When creating a new code, you have the option of choosing a custom color. By default, the system chooses the colors for you as you work. However, for our users that are more visually inclined and like to keep things arranged in a particular way you may want to control the colors and which codes are associated with which colors. You will need to set the color scheme for your codes to 'custom' from the settings panel in the code tree. You will also want to be careful to choose colors for each code, as the default color is black and having a dozen codes all show up black can be a bit obscuring.
Automatic upcoding applies the parent of any child code at the time the child code is applied to an excerpt. By default, this is deactivated and applying a child code to an excerpt will only apply that specific code.
Retroactive upcoding checks every excerpt in a project and applies parent codes to excerpts that have a child code applied, but not the parent code. Note that anytime you decided to use this feature, you might want to first make a copy of the project as a backup in case the result of the procedure is not what you expected or desired.
The fastest way to create codes and code excerpts is with the Quick Code Widget. This feature allows the use of keyboard shortcuts to maximize efficiency when coding text documents. Here are the steps to use this awesome feature:
When you apply a code with the Quick Code Widget: once the first code is applied, the ’Selection Info’ panel in the upper right corner will change to orange to indicate you are in excerpt editing mode and where information about the excerpt will appear.
Codes with Shared Subtext
If you have multiple codes that appear with the same subtext, typing into the search field may leave you with both so you can use the arrow keys to scroll down the list of codes and hit ‘Enter’ to apply the highlighted code of choice.
Adding a New Code with Existing Subtext
To add and apply a new code that’s title exists within the subtext of existing codes (ex. ‘reading duration’ and ‘reading frequency’ exist as codes and you wish to create new code called ‘reading’), type the name of the new code and use the command ‘Shift’ + ‘Enter’ to create the new code and apply it to the excerpt (where clicking ‘Enter’ alone will serve to apply whichever existing code that is highlighted after you've typed the name of the new code).
Finally, note that the Quick Code Widget is a movable and sizable panel. Leaving the panel open means it does not need to be reactivated for each excerpt or document you are coding.
Code/Tag systems can be imported and exported to and from MS Excel (and other formats) and exported to MS Word with the option to also export all coded excerpts. This feature can be helpful in the preparing of reports and for sharing code systems from one project to another.
Exporting codes to a Word format also allows you to include all excerpts associated with each code, so is a quick way to export all project excerpts organized by the code tree.
Note that you can also import and export codes with the 'Import Data' button and 'Export Data' buttons on the Home Dashboard.
Here is an example of what the code system looks like in Excel:

Excerpting and Coding Text Documents Manually
Excerpting and coding can also be done through a multi-step process. This is the best option if: you wish to create excerpts prior to developing your code system, if you are looking to build a hierarchical structure to your tree as you move through the excerpting process, or if you wish to take advantage of the document cloning feature.
Document Viewing and Excerpt Creation
Editing Excerpt Length:
Excerpts within audio, video, images and PDF files are editable by adjusting the boundaries whenever selected, however text excerpts are changed with a different set of steps:
Code weighting can be activated for use at any time. It is often the case that a meaningful code weighting system will not emerge until the nuances of meaning in the data become clearer to the research team. That is, while scalable distributions of a code may emerge when sufficient data has been examined, a useful and precise weighting scale definition and application criteria often only follows a certain amount of preliminary data exploration. Accordingly, it is often preferable to begin the coding of excerpts either without defining a code-weight system or by simply accepting a weight default value. Following adequate data analysis and weight scale definition, the weighting scale can be meaningfully defined and the user can then return to previously coded excerpts to set the weight according to the newly defined system.
Code Weight Auto-applying:
Applying codes with code weights to a number in documents will automatically apply that number as the code weight if it is within the range defined by the code weight minimum and maximum values you defined.
Screenshot of Video Viewer
The process for creating and coding excerpts on audio or video streams is similar to text except you will see either a sound wave or video in the media viewer.
Keyboarding has been enabled for some of the most frequent audio and video excerpting activities:
Dedoose makes it easy for you to import existing media files for your qualitative data, regardless of whether they are stored as spreadsheets, text, images, audio, or video.
These data may be field notes, observations, interview or focus-group transcripts, manuscripts, pasted images, audio streams, photographs, video streams, hyperlinks, survey data—anything that you can store as a text, spreadsheet, audio, or video file (.doc, .docx, .rtf, .txt, .pdf, .xls, .xlsx, .csv, .tif, .jpg, .png, .gif, .mp3, .mp4, .wma, and .m4a).
To import your files, start from the Project Workspace dashboard and click the Import Data icon in the upper left panel. You will then see a pop-up menu where you will indicate the type of data you are importing. Locate the files and submit. Note that you can also import data in many of the other Workspaces.
The Dedoose Survey importer is one of our proudest achievements. This will take an existing data set in excel and transfer all the data into Dedoose. While powerful and intuitive, our survey importer works best when you follow the format discussed below.
Survey to Dedoose Project Creation
Creating fully populated Dedoose projects from SurveyMonkey or other data collection service output is an increasingly popular feature in Dedoose. Here's an overview and instructions on how to prepare data from survey responses and open-ended questions stored in an Excel file. Two main things to note:
To make this process most efficient and the results most useful, here’s what is required/recommended:
_ddqual_ to both force qual fields and to force titles for your docs
The survey import tool generally does a great job distinguishing close-ended descriptor data from narrative responses. The algorithm for doing so depends on what is found in a column based on the number of unique values (ex. gender would be 'male' or 'female') and the number of characters. Occasionally, you may have a qualitative field that has short responses or similar responses across participants that is misread as a descriptor field instead of an open ended field. For cases just like this, our Tech Team built a way for you to force the system to recognize these fields as qualitative:
Consolidating columns with the same title in a spreadsheet file:
Importing your data into Dedoose via a spreadsheet automatically defines descriptor fields, creates descriptors, creates codes, converts any narrative responses to tagged excerpts within a document for each case, and links the document to the appropriate descriptor. The importer does this by checking each column title, examining the data in each column, and then uses this information to parse the data. Should you have column titles that are not unique, the system will automatically consolidate them into the same question.
To learn about our recommendations on how best to prepare your data for import, please see Working with Media section of this user guide.
Code weights or ratings can be defined and applied to indicate anything that can be represented on a numerical dimension including quality, sentiment, importance or any other dimension that can help distinguish variation in content where the same code has been applied to sets of excerpts. Dedoose also has a variety of charts that draw directly on these dimensions to expose patterns in both the excerpt content and the investigator determined ‘quality,’ ‘sentiment,’ ‘importance,’ or anything that you’ve decided to index across a code weight/rating system. To learn how to define code weights/ratings, see the Code Tree section of this user guide.
Incorporating code weights/ratings in your project allows you to bring an entirely independent dimension to your database. For example, say we are interviewing parents about what it looks like when they read to their preschool aged child. We might also ask parents to report on a 5-point scale (1 = poor to 5 = excellent) for the quality of their reading. However, parents only know how they read and maybe how a few other people read…and self-reports are subject to a social desirability influence where research shows people tend to over report on positive characteristics or behaviors and under report on negative. As investigators, however, we see all excerpts where parents talk about reading to their child. This perspective lets us see the full range of what reading looks like in the entire research sample and allows us to lay out all the excerpts across a rating scale that we use to index ‘quality’ of reading. Here are a few things to keep in mind as you consider using this feature:
Excerpts can be retrieved, reviewed, recoded, and exported from many places in Dedoose. These locations include the Excerpt Workspace and the chart selection reviewers that pop-up to show all the active excerpts (‘Hits’) after filtering or drilling-down to the sets of excerpts sitting behind any of the charts, tables, and plots—see the section on analysis for more on how clicking on portions of charts, tables, and plots, pulls up the excerpts represented in the visualizations.
In the Excerpt workspace, users can sort and filter sets of excerpts to narrow the focus of an investigation and then review individual excerpts via the SuperMegaGrid. For example, in the following Excerpt Workspace screenshot, excerpts have been filtered to those which meet the following criteria: ‘Not Working’ or ‘Part Time’ working fathers, of ‘Hispanic’ origin, and with ‘Female’ children and then sorted by code (as indicated by the arrow in the ‘Codes Short’ column). This was accomplished by the following steps:
Filtering excerpts in this manner can be very convenient when searching for specific sub-sets of excerpts to explore or export across a larger number of criteria.
The next screenshot shows an excerpt that had been opened for full review (by clicking on the excerpt in a reviewer or list). This view allows you to:
Excerpt Review, Recode, and Export after Filtering
As has been introduced earlier (and also discussed in the Filtering and Analysis section), reviewing and exporting filtered excerpts is an intuitive and transparent process in Dedoose. The following screenshot shows part of the Dedoose Home Dashboard where one of the basic charts in Dedoose are shown with the information that appears when floating over one of the bars. Here we see the relative frequency the ‘Reading by Mother’ code was used across ‘Mother work status’ groups. The smart tip shows the metrics on the highlighted bar (Part Time working Mothers) with reference to all excerpts with the same code.
Clicking on this bar, activates a pop-up Chart Selection Reviewer containing the set of excerpts sitting behind (and represented by) the bar in this chart. The following screen shot shows this list and a pop-up containing the text of the first excerpt which has been highlighted by floating the cursor over the excerpt.
From this listing, excerpts can be quickly:
