Section 1: PCA analysis
We provide a step by step example of how we conducted the PCA analysis.
Assume we have 8 odors, each located on the vertexes of a 3 dimensional unit cube.
Each odor can thus be represented by the exact binary code of the numbers 0 to 7.
We can represent these odors in the following binary code matrix:
Odor ID Pattern code:
1 0 0 0
2 0 0 1
3 0 1 0
4 0 1 1
5 1 0 0
6 1 0 1
7 1 1 0
8 1 1 1

Using any available mathematical tool (we used Matlab 'princomp' method) we can calculate the principle components scores of this matrix. In this case the values of the
PC1 scores are: [1 0 0]. The PC1 projection value of each row is the projection of each row by the PC1 weight vector. For example the PC1 value of the first row is
[0,0,0]X[1,0,0] = 0X1 + 0X0 + 0X0 = 0. (this is a vector multiplication). Thus the
PC1 value of each row of this matrix is: 0,0,0,0,1,1,1,1. Note that usually the PC1 is calculated on a centered matrix (the columns of the matrix have zero mean) and thus the PC1 value might be shifted by some value. The same calculations are applied for the higher PCs.
Section 2: Neural correlates of PC2
PC2 is orthogonal to PC1, that is
Section 3: Global neural computation is less susceptible to lesions and gene ablations
According to the suggested PCA based computation of odor preference each odors' neural response is projected on the first PC value. Thus, the score of an odor is a weighted sum of the neural responses. Consider two odors A and B, that each generated a different neural pattern. According to our computation the odor index of
2 Haddad Supp pp 3
A is A*PC1 and the odor index of B is B*PC1. Odor A is considered more attractive if A*PC1 > B*PC1 or if (A-B)*PC1 > 0. In case of random gene ablation of bulb lesion the resulted neural pattern of both odors A and B can be marked A' and B'.
However we still get that (A'-B')*PC1 > 0 and thus odor A will still be more attractive than odor B

Supplementary Figure 2. Constructing human odor perceptual space
Human odor perception can be described by representing each odor by the average ranking assigned to it using a large set of verbal odor descriptors. For example,
Hexanal is very pungent, medical and heavy whereas Carvone is minty and flowery.
This high dimensional representation of human odor perception can be reduced to a lower dimension using PCA. Thus each odor can be represented by its PC1 and PC2 values.

Supplementary Table 1: The odor response index for Drosophila larvae and adult.
For Drosophila Larvae we took the data reported in (Kreher et al., 2008) (including odors reported in the supplementary information). For Drosophila we searched the literature for Drosophila behavioral data under similar conditions (1/100 dilution in mineral oil and T-maze attraction repulsion test limited to less than few minutes). We found data for nine additional odors. Among these nine odors, two odor scores were similar to the larvae's scores, two odors had different scores and five odors did not have any larvae scores.

20 odors and their average pleasantness ratings as rated by 18 subjects.
Supplementary Table 3: Rat and mouse oral toxicity
List of odors and the oral toxicity of rats and mice reported as LD50 in mg/kg. In cases of multiple sources we took the average value or the latest source. Values above
35000mg/kg are not LD50 values, but rather TDLO values (lowest published toxic dose) in mg/kg/3w, and were thus not included in the analysis. LD50 values listed as
-1 or -2 denote no available value.
