plot(modes, pdbs=pdbs, col=col). Error in e[, "start"] : incorrect number of dimensions

I'm following the NMA tutorial described in http://thegrantlab.org/bio3d/tutorials/normal-mode-analysis using my own PDB Ids.

I'm able to generate structure alignment, and generate modes. print(modes) gives: Call: nma.pdbs(pdbs = pdbs)

Class: enma

Number of structures: 9

Attributes stored: - Root mean square inner product (RMSIP) - Aligned atomic fluctuations - Aligned eigenvectors (gaps removed) - Dimensions of x$U.subspace: 294x288x9

Coordinates were aligned prior to NMA calculations

attr: fluctuations, rmsip, U.subspace, L, full.nma, xyz, call

When I try to plot I get:

col <- c(1,1,1, 2,2, 3,3, 4,4) plot(modes, pdbs=pdbs, col=col) Extracting SSE from pdbs$sse attribute Error in e[, "start"] : incorrect number of dimensions

Although this issue was previously reported fixed, it is not in my case.
