NVivo 8: Vista and XP coding anomaly


Recommended Posts

Hi,

 

I'm using NVivo8 on Windows XP (desktop) and Vista (laptop). While coding the same project, I've noticed that executing exactly the same procedure on both systems while coding an identical internal document will produce different results:

 

The internal documents are questionnaires, first auto-coded by paragraph style and then further coded.

 

I've just tested this out so that I could post to the forum:

 

Document A has Nodes-25 References-25

 

On XP, I select some text.

Then 'Code selection at existing nodes'.

Choose Tree Nodes.

Select tick box for 1 parent category and 1 child category.

This results in Nodes-26 References-27 (i.e., Nodes+1 and References+2)

 

On Vista, if I do exactly the same thing, the results will be Nodes-26 and References-26 (i.e., Nodes+1 and References+1).

 

The only way to get both systems behaving the same way, is to tick only a child category in XP (and not parent and child as I can in Vista). I really don't understand why Vista and XP produce different results for identical documents using an identical procedure. I'd be grateful if someone could help me to understand why this is happening. Many thanks.

Hi Susan,

 

Your problem sounds very interesting. Is your project a single user project or multi user project? If you have been using the same project on XP and Vista, do you have same user name for NVivo 8 on those 2 machines? You can open up Application Options to find out the current user name, and turn on User Coding Stripes to find out who has coded this document. Please be aware that overlapping coding by 2 different users will be counted as 2 references in NVivo, while overlapping coding by 1 user (at the same node) will be merged and counted as 1 reference.

 

However, even if you had multiple users' coding in that document, it still doesn't explain why the number of nodes are different after coding the same selection to the same nodes, if the original documents have exactly the same coding. Susan, may I know if you have used the same copy of project to run this test on XP and Vista? If you have used 2 different copies, then any slight difference in coding or anything else might make a difference.

Hi Claire,

 

Thanks for this reply.

To further clarify:

1. My project is single-user. I'm not researching as part of a team, and I simply refer to myself by my initials 'SB'. This is the only 'user' I can find in my project file.

2. In order to confirm my suspicions about what the programme was doing on both systems (XP and Vista), when using the same project file, I created another copy of it and renamed it 'trial' and then used this to ensure I was doing exactly the same thing on both computers - and it was producing the anomalous results. The project used ('trial') was thus identical.

 

As I understand it, then, given your statement that "overlapping coding by 1 user (at the same node) will be merged and counted as 1 reference" the example on Vista shows the programme working as it should, and the one on XP - which consistently adds an extra reference - is producing results that are a bit mysterious?

 

I'm still very confused about this issue, and a bit hesitant in proceeding with coding on the two different operating systems. Can this be replicated at all in a test environment, or is it related to issues in my specific internals documents (and perhaps earlier coding done on those)?

 

Many thanks, Susan

Have just looked into this issue again. It seems that there are in fact two 'SB' users one 'SB' and one 'S B' - this has happened inadvertently, I don't know how it happened (the SB one looks like a default setting because it is using the name 'Compaq_Owner' which is not something I would have called myself!) and I didn't want 2 users in the project. How can I merge them? And is this the reason for the apparent anomaly I've noticed when coding?

 

Many thanks.

Hi Susan,

 

This might be the reason for the inconsistent results on 2 computers that you've noticed. When NVivo launches for the first time, it will ask you to enter user name and initials. However, there will be a default user name displayed, which is your Windows user name on that computer; if you don't choose to change it, it will be your NVivo user name. If you then open a project and do coding etc. in that project, this NVivo user will be recorded as one of the project users in that project. I guess 'Compag_Owner' might be the Windows user name which you have used on one of those computers. To fix your NVivo user name on that computer, please select from main menu Tools -> Application Options, and change User Name on that dialog. However, this will not fix any existing coding in your project.

 

You cannot merge users in the current version of NVivo 8. However, it might be not that hard to fix the coding manually, if majority of coding is under one of the users. To find out the details about different users' coding, you might find some tools useful, such as Coding Comparison Query, Coding Query, User Coding Stripes, etc. Once owner is identified for each piece of coding, you can choose to uncode for selected user and re-code after your user name on Application Options is fixed.

 

By the way, in NVivo, users are identified by user name, instead of initials. So if 2 users have 2 different user names, then they will be considered as 2 different users, even if they have same initials.

 

Does it make sense to you?

Hi Claire,

Thanks for your reply. I've sent you a message about this, as it seems there are further factors complicating the scenario I find myself in relating to this issue, and because it seems that fixing it won't be straightforward.
