QTL detection for GABA (a) and Maltose (b) using CIM and NCR when the guiding dataset is SNP data. GABA and Maltose share an edge in both \({\varvec{W}}(\hat{{\varvec{Y}}}^{M}({\varvec{X}}^S))\) and \(\hat{{\varvec{W}}}({\varvec{Y}}^{M})\) which can be justified by their QTL profile. The \(-\log _{10}\) p-value score for every marker is plotted when CIM is used. The red dotted vertical lines are plotted as a visual separation between the 5 chromosomes and the chromosome number is indicated on the x-axis below each segment. The dotted horizontal blue line marks the \(-\log _{10}\) p-value score of 3. Red dots on the x-axis are placed on marker positions for which NCR estimated non-zero coefficients. The color transparency indicates the magnitude of the regularized estimated coefficient. The correspondence between CIM and NCR can be seen by noticing that red dots on the x-axis are in most areas where the \(-\log _{10}\) p-value score has high values
