I'm using metaSEM package developed using OpenMx for conducting meta-analytical structural equation modeling (http://courses.nus.edu.sg/course/psycwlm/Internet/). When applying the mxModel (through tssem1RE function in metaSEM) to my data, I receive a message about an error in runHelper saying that "Requested improper value (5, 41) from (4, 702) matrix" and the function is terminated! I have attached a snapshot of the error message.
Can anyone help me to resolve this error and what can be the possible cause of this error? Is it a known error in OpenMx? I'm new to OpenMx and do not have much knowledge of it!
I'm using R version 2.15.0 and OpenMx version 1.2.4 for Windows.
Any help would be really appreciated,
