Problems with networks with no single hybridization

[acosta187]

Hello Joe,

I am working with networks simulated in R with "SiPhyNetwork" and then converted in hybrid lambda format with julia, but when I use hybrid lambda it can not produce gene tree in some "networks with no single hybridization", and give me that mesage: "Segmentation fault (core dumped)", and "Error: basic_string::substr: __pos (which is 926) > this->size() (which is 925)" in other verssion. This is one network that give in trouble.

Hi @acosta187 . I will try to have a look on that. Would you mind sharing the exact command that led to the error? :)

Hi @Becheler this is my procedure to run hybrid lambda with simulated networs by "SiPhyNetwork". I notice that the problem happen in some network that have "no single hybridization" (like the network that I put in the example) or in cyclic reticulation (when hybridization occurs when two parts of the same branch join, Sorry but I don't remember the exact term).

Network generated with "SiPhyNetwork":

Hybrid lambda code:

hybrid-Lambda -spcu 'hybridlambda_filename' -num 100 -seed 865014 -o name_file_save_gt > saving_hybridlambda_message 2>&1

can also be run by placing the net directly:

hybrid-Lambda -spcu '((((t13:0.1074074245,t16:0.1074074245)I1:1.118068408,t1:1.225475832)I2:0.8643459005,H26#0.1653593469:1.455801779)I3:0.05799997902,((t10:0.8663279768,((t15:0.3768871335)H29#0.9524025219:0.25713282)H26#0.1653593469:0.2323080233)I4:1.165560728,(((((t7:0.2259815159,t11:0.2259815159)I5:0.06516197373,t9:0.2911434897)I6:0.08574364385,H29#0.9524025219:0.0)I7:0.3388649192,(t2:0.3776026943,t4:0.3776026943)I8:0.3381493583)I9:0.6381163571,((t14:0.04168772354,t6:0.04168772354)I10:0.0561034575,((t12:0.0202606947,t5:0.0202606947)I11:0.0200718446,t3:0.0403325393)I12:0.05745864174)I13:1.256077229)I14:0.6780202951)I15:0.1159330068)I16;' -num 100 -seed 865014 -o name_file_save_gt > saving_hybridlambda_message 2>&1

and the result is:

Wonderful, thanks it's very helpful!
