I would like to create a new node for sources that have not been coded to certain other existing nodes. For example, let's say I have 10 sources. I have coded 2 to the node "yellow" and 3 to the node "red." I would like to create a node that automatically captures the remaining sources that have not been coded to either "yellow" or "red." Is this possible? Thanks, Austin

Hi, I am trying to use matrix queries to do some cross tabulation style analysis. Is it possible to use a matrix coding query to see nodes that are matched up with other nodes based on multiple attribute values? In other words, I would like to define my "row" as having a "node classification" attribute value of, say "Hair Color"="Brown" AND "Gender"="Male". Each of my respondents has been coded to a node (name of respondent) that has been attributed to the node classification sheet that includes both Hair Color and Gender. Then, my column would be defined as whatever node I am interested in, so that I can see how many of those nodes match up with respondents who are male AND have brown hair. Make sense? Thanks! Austin

Hi Marcus: I've run into another little issue with "totals." I am running a matrix coding query. I've created an attribute called "total" and assigned all the attribute values as "total." I am now trying to run a query that includes a column for the totals of each attribute value that I've specified in my search. I also have an attribute called "DMS," which consists of three distinct values: mid, central, and peripheral. In the attached, I only have 57 nodes assigned to the classification. Each node is given an attribute value of "mid," "central," or "peripheral" for the attribute "DMS." Each of the 57 is also assigned the value of "total" for the "totals" attribute (that's the column heading that you can't see). Any ideas why this adds up to 60 when matrix coding on the attribute DMS for the three values (10+20+30), instead of adding up to 57? I have chosen to see the cells by Cell Content>Nodes Coded> (the classification sheet that I am using for all of this). When I assign all the attribute values as the same, I get the correct total (57). BUT, when I choose three separate attribute values, I get a total of 60. Many thanks! Austin Untitled.tiff

YES!!! Thanks so much! What a time saver!!

I have set up about 60 nodes for some key words in my source files. Some of those nodes already have content coded to them, others do not. I am wondering if there is a way to do a "bulk" text search for all of these node/key words? Or, do I have to do 60 individual text search queries? Thanks as usual! Austin

Hi there, I am creating charts of nodes. I'd love to just use the charts/graphs within NVivo, but I find they have lots of issues: - When I visualize results of a matrix coding query as a chart, the only option is the 3-D chart. -Often, the names of the nodes are cut off at the bottom of my screen, despite how far out I zoom. -I cannot change the type of chart (I'd like a bar chart with side-by-side bars for my attribute values, instead of a 3-D chart. I find the 3-D charts hard to read) - I cannot change axis labels, titles, or any other feature within the chart - It is also very confusing to try to decipher what the values in the charts represent. For example, when I run a matrix coding query, I get results for "coding references" that are different than the "references" identified within the node itself. - Running a query is a clicking-intensive experience. For example, when generating a matrix coding query, defining each row takes several clicks. For example: Choose "Define More Rows" by Attribute Condition > Select > Select > Node Classifications > (Classification sheet) > Attribute > (Attribute Value) > OK > Add to List Then, the whole exercise again to pick a second, third, fourth attribute value and more to do it again for columns. Finally, there is no way to save the query. I end up exporting my matrix coding query and charting the results in Xcel. But, each time I rerun the query or make a change in my nodes, I have to re-export the results. I end up with many, many, spreadsheets in Xcel. Best would be some better charting functionality within NVivo, so that basic charting doesn't need to be done in Xcel at all. Thanks!

I am not sure if the latest update to NVivo solved this problem or if it was solved by switching to a SSD drive. In any case, NVivo has gotten MUCH more stable for me. It still occasionally crashes when I ask it to carry out something very complex, but even when it does I no longer get the "corrupt file" problem. This is a huge relief!

How about a way to save a coding query? Then when you make changes in other parts of your data, you can still go back and rerun queries without having to do all the setup steps again. Thanks! Austin

When generating a matrix coding query, defining the rows and columns is quite clunky. As it is now, each row takes several clicks. For example: Choose "Define More Rows" by Attribute Condition > Select > Select > Node Classifications > (Classification sheet) > Attribute > (Attribute Value) > OK > Add to List Then, the whole exercise again to pick a second, third, fourth attribute value and more to do it again for columns. How about a cut and paste function in the list? That way one could cut and paste and then simply change the attribute value without going through all the above steps. Thanks! Austin

Hi all, I have been running lots of Matrix Coding Queries. I find the charts within NVivo to be pretty clunky and have been exporting individual query results to Xcel so that I can make better charts/graphs. I end up with a HUGE number of spreadsheets. I can, of course, do lots of cut and pasting into worksheets of a common spreadsheet file in order to keep things a bit more under control. But, this is time consuming. I'm wondering if anyone has developed a system for keeping things organized? Thanks! Austin

Thanks!

Yes, many thanks.

When doing a matrix query, there are a number of options for viewing the results. I've looked in the help menus, but can't find an explanation for the various terms referred to: Under "cell content"... Nodes coded - all classifications Nodes coded - no classifications Nodes coded - [classification sheets listed] Coding references Row percentage Column percentage Are these terms explained someplace and could someone point me to it? Thanks!

If I have 10 child nodes all assigned to a classification sheet (with various attribute values) and I aggregate their parent node (and assign the same classification sheet), how does the parent node handle the attribute values?

Hi Marcus - Still a bit confused on how to interpret these options. For example, when I choose to view cell content for a given node in my matrix as "coding references" I get a value that is HIGHER than the value of all the references coded to the given node. How can this be? Thanks again, Austin
